It is set when the platform exposes the struct ucontext_t.
This avoids duplication of logic inside each package requiring
the use of that type.

This commit backports an upstream commit adding RISC-V support to
libsigsegv, and adds a patch that finalizes the RISC-V support to make
it compatible with cross-compilation.

We want to use SPDX identifier for license strings as much as possible.
SPDX short identifier for GPLv2/GPLv2+ is GPL-2.0/GPL-2.0+.
This change is done by using following command.
find . -name "*.mk" | xargs sed -ri '/LICENSE( )?[\+:]?=/s/\<GPLv2\>/GPL-2.0/g'

While musl and glibc provide the ucontext structure definition on all
architectures they support, it is not the case of uClibc. We have been
excluding more and more architectures over time, but this isn't really
nice as we continuously need to add more. Latest example: the fact that
ucontext on ARM is only available on ARM platforms that support the ARM
instruction set (i.e not on the Thumb-2 only Cortex-M platforms).
Therefore, we introduce a BR2_PACKAGE_LIBSIGSEGV_ARCH_SUPPORTS variable,
which:
- is set to 'y' for musl and glibc
- is set to 'y' for uClibc for the only architectures that are known to
provide ucontext (those are the ones that select ARCH_HAS_UCONTEXT in
uClibc.
Note that we remove the comment, as it would become a way too
complicated comment, and we usually don't add comment for such
complicated situations (see libunwind for a similar example).

Following the removal of eglibc support, this commit replaces all
occurences of "(e)glibc" by just "glibc". Most of the occurences are in
package Config.in comments.
In addition, when the form "an (e)glibc ..." was used, it is replaced by
"a glibc ...".

Like PowerPC, the uClibc port on SuperH doesn't implement ucontext, so
we can't build libsigsegv in such a configuration. Therefore this
commit marks libsigsegv as not available on SuperH/uClibc.

The libsigsegv configure step fails to correctly figure out the direction of
stack growth for avr32. This leads to a zero STACK_DIRECTION definition, and
build failures such as the following.

The configure script doesn't detect that the target is posix-compliant
and tries to use a custom version of segfault analysis that actually
doesn't build. Most likely, it's because the configure script doesn't
support linux-3.x. Anyway, we can just tell configure that we're
posix-compliant.
