Detecting the boost program_options library is broken:
checking for the Boost program_options library... no
configure: error: cannot find the flags to link with Boost program_options
config.log shows the reason, libatomic is missing:
conftest.o: In function `boost::detail::sp_counted_base::release()':
conftest.cpp:(.text._ZN5boost6detail15sp_counted_base7releaseEv[_ZN5boost6detail15sp_counted_base7releaseEv]+0xc):
undefined reference to `__atomic_fetch_sub_4'
conftest.cpp:(.text._ZN5boost6detail15sp_counted_base7releaseEv[_ZN5boost6detail15sp_counted_base7releaseEv]+0x38):
undefined reference to `__atomic_fetch_sub_4'
/home/buildroot/br4/output/host/sparc-buildroot-linux-uclibc/sysroot/usr/lib/libboost_program_options.so:
undefined reference to `__atomic_fetch_add_4'
Please note that using LIBS=-latomic is not enough, although it fixes
the configure check the bug reoccurs when linking cc-tool:
CXXLD cc-tool
src/application/cc_flasher.o: In function `boost::detail::sp_counted_base::weak_release()':
cc_flasher.cpp:(.text._ZN5boost6detail15sp_counted_base12weak_releaseEv[_ZN5boost6detail15sp_counted_base12weak_releaseEv]+0xc):
undefined reference to `__atomic_fetch_sub_4'
We need to add -latomic to CXXFLAGS to both fix configure and linking.

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'

The BR2_PACKAGE_BOOST_ARCH_SUPPORTS option was originally added in
commit feeab03fa6 to be able to disable
Boost on broken NIOSII CodeSourcery toolchains.
However, since then, the CodeSourcery toolchain has been updated, and
once the fenv problem is fixed, this NIOSII toolchain is capable of
building Boost.
Thanks to this we can completely get rid of the
BR2_PACKAGE_BOOST_ARCH_SUPPORTS symbol, from boost itself and from all
its reverse dependencies.

The version of boost.m4 initially included in cc-tool has an issue
with gcc5 (one of its tests fails due to the first change described in [1]
"Preprocessor issues").
This was fixed upstream (boost.m4 project) in Nov 2014 [2].
We add the latest commit [3] of upstream boost.m4 plus a patch from github PR
[4] to add detection for gcc 5.1.

The current NIOS 2 toolchains are not capable of building Boost, so
let's disable it and its reverse dependencies. Even though it's not
strictly an architecture dependency, we use the <pkg>_ARCH_SUPPORTS
paradigm for this dependency, since it simplifies a lot handling all
boost reverse dependencies, and is anyway quite similar to an
architecture dependency since we don't display a comment about this
dependency.
