glibc toolchain using gcc 4.9.

* lex.c (search_line_fast): Remove illegal coercion of an
unaligned pointer value to vector pointer type and replace with
use of __builtin_vec_vsx_ld () built-in function, which operates
on unaligned pointer values.
The patches included in Buildroot contain just the code changes, and not

gcc-8.1 for xtensa miscompiles uClibc dynamic linker due to gcc PR
target/65416. The build completes successfully, but the binary is
non-functional because the following fragment in the _dl_get_ready_to_run
in ld-uClibc.so overwrites register spill area on stack causing register
corruption in the previous call frame and a subsequent crash:
419f: f0c1b2 addi a11, a1, -16
41a2: 1ba9 s32i.n a10, a11, 4

41af: 146af2 s32i a15, a10, 80
41b2: 001b10 movsp a1, a11
The crash terminates the init process and causes kernel panic.
The fix prevents reordering of movsp opcode and any access to the stack
frame memory and is applicable to all existing gcc versions.

The HOST_GCC_COMMON_WRAPPER_TARGET_FLOAT_ABI variable was incorrectly
used as HOST_GCC_COMMON_WRAPPER_TARGET_FLOATABI_, which would always
be empty.
In practice, this block of code is only used on Blackfin (which has
BR2_GCC_ARCH_HAS_CONFIGURABLE_DEFAULTS unset) and Blackfin doesn't use
float-abi, so this block of code is in fact useless. But even if it's
useless, it's better to have it without typos.

This merges the next branch accumulated during the 2017.11 release
cycle back into the master branch.
A few conflicts had to be resolved:
- In the DEVELOPERS file, because Fabrice Fontaine was added as a
developer for libupnp in master, and for libupnp18 in
next. Resolution is simple: add him for both.
- linux/Config.in, because we updated the 4.13.x release used by
default in master, while we moved to 4.14 in next. Resolution: use
4.14.
- package/libupnp/libupnp.hash: a hash for the license file was added
in master, while the package was bumped into next. Resolution: keep
the hash for the license file, and keep the hash for the newest
version of libupnp.
- package/linux-headers/Config.in.host: default version of the kernel
headers for 4.13 was bumped to the latest 4.13.x in master, but was
changed to 4.14 in next. Resolution: use 4.14.

Upstream gcc now has support for ARC, as of 7.x, with 7.2 being
usable, so let's allow its selection.
GCC from Synopsys GitHub still has a lot of fixes and improvements
most of which will be a part of the next upstream release but let's
see how it goes and if we see vanilla GCC doesn't require way too many
back-ported patches we'll be able to get rid of Synopsys GitHub here
at all.
As of today the only really required back-port is the one for non-uClibc
libc.

Currently the possibility to choose the NaN encoding is conditional to
having a sufficiently recent gcc version.
Which means that the architecture selection depends on the gcc version.
But that's opposite to what we've always done in Buildroot: the software
versions are conditional to the architecture options. There is nothing
we can do about the hardware: it is there, we can't change it, while we
can restrict ourselves to using software that is working on said
hardware.
Thus, we inverse the logic, to move the condition onto the software
side: whenever NaN-2008 are selected, we restrict the toolchain
selection to at least a gcc-4.9.
But now, the option with the NaN type is always set, so we must enclose
the code in gcc.mk inside a HAS_NAN_OPTION condition, as is already done
for the external toolchain case.

Take the conditions currently specified in the gcc version choice.
Also, the conditions explained in the commit log for 78c2a9f7 were not
all properly applied, especially the a57-a53 combo needs gcc-6, but
78c2a9f7 forgot to add the condition to gcc-4.9.
gcc-4.9 was excluded for cortex-a17 and a72, but the CodeSourcery
external toolchain, which uses 4.8, was not excluded for those two
cores. Now it is.

We use the conditions currently expressed in the gcc version choice.
We leave the musl vs mips64 conditions in gcc, because the "fault"
really is on gcc, which does not recognise the mips64+musl tuples,
so the fix lies within gcc, and the current conditions are fitting.

Begin the conversion from hard-coded dependencies on architectures, to
architecture-specified version requirement, using the newly introduced
BR2_ARCH_NEEDS_GCC_AT_LEAST_XXX symbols.
Hard-coded dependencies will be removed progressively, as archs are
individually converted over to using the new symbols.
We do not change the architecture-specific versions for ARC and
OpenRISC, because there is no point in doing so for those, as they use
special, non-upstream versions anyway.

GCC 4.9.x requires an old version of ISL to support graphite, and this
old version of ISL is not sufficient to support graphite in modern GCC
versions.
Since GCC 4.9.x is getting older, and to keep things simple, we stop
supporting graphite on old GCC < 5.x. This way, we will be able to
bump ISL to a version that is suitable for modern GCC versions.
In addition, this allows to drop the dependency on cloog, which was
only needed for GCC 4.9.

MIPS32 support different FP modes (32,xx,64), so give the user the
opportunity to choose between them. That will cause host-gcc to be built
using the --with-fp-32=[32|xx|64] configure option. Also the
-mfp[32|xx|64] gcc option will be added to TARGET_CFLAGS and to the
toolchain wrapper.
FP mode option shouldn't be used for soft-float, so we add logic in the
toolchain wrapper if -msoft-float is among the arguments in order to not
append the -fp[[32|xx|64] option, otherwise the compilation may fail.

MIPS supports two different NaN encodings, legacy and 2008. Information
about MIPS NaN encodings can be found here:
https://sourceware.org/binutils/docs/as/MIPS-NaN-Encodings.html
NaN legacy is the only option available for R2 cores and older.
NaN 2008 is the only option available for R6 cores.
R5 cores can have either NaN legacy or NaN 2008, depending on the
implementation. So, if the user selects a generic R5 target architecture
variant, we show a choice menu with both options available. For well
known R5 cores we directly select the NaN enconding they use.
