The pylibfdt in dtc is new since 1.4.5, and therefore built since the
bump from 1.4.4 to 1.4.7 in commit
7b929ddcf0. Unfortunately, this Python
support causes a number of build failures, be it for host-dtc or dtc.
Since this Python support is not used/needed by anything in Buildroot
at this point, let's simply disable it by passing NO_PYTHON=1. While
doing this, introduce DTC_MAKE_OPTS and HOST_DTC_MAKE_OPTS to avoid
duplicating the variables several times.
Fixes:

The "install-bin" target just installs dtc's programs to host/bin
without libfdt, but building qemu system requires libfdt.
see: https://gitlab.com/c-sky/buildroot/-/jobs/38654503
So we need to install libfdt to satisfy the requirements of qemu.

everything keeps on working.

Adds overlay support.
Drop the non-upstreamed 0002-extra-cflags.patch and instead simply pass the
needed CFLAGS as make arguments. Passing the full upstream warning flags
are not important in the Buildroot context, so this is simpler than
maintaining a patch.

This reverts commit 5ca9b7cf66. Installing
dtc headers in $(HOST_DIR) causes some build failures of
host-uboot-tools due to a conflicting libfdt.h header.
The possible solution to solve this problem, based on -isystem, has been
reverted has it was causing too many issues that we didn't want to solve
so close to cutting 2016.08-rc1.
Since the headers of libfdt for the host are currently not needed for
any package in the Buildroot tree, it is easier and safer to just revert
this patch.

Having a host variant of dtc is needed for example for U-Boot, which
uses the Device Tree for a number of platforms.
In addition, now that we have a proper host-dtc package, it is no
longer needed for the linux package to install the host dtc compiler:
users interested in having the host dtc compiler can simply enable
this package.
A Config.in.host option is added to build host-dtc, because the
initial reason why the host DTC built by the kernel was installed in
$(HOST_DIR)/usr/bin (commit 707d44d0a2
from Thomas DS) was:
Having dtc as a host tool can be useful for users that have a
custom boot scenario where the device tree is not embedded in the
kernel.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.
