Bernd Kuhls 8d6371f512 package/cc-tool: link with libatomic when needed
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.
