Damien Le Moal 01932fec17 package/gcc: Fix gcc finale library installation 
Fixes:
http://autobuild.buildroot.net/results/98f/98fedf4969c260f73a01b937b9625e66dcd86b3c

When BR2_TOOLCHAIN_HAS_LIBATOMIC is "n", there is no gcc libatomic.so
library to install. For configurations with such settings, compilation
fails as gcc-final.mk unconditionally adds libatomic as an installation
target. This error, for instance, shows for all Canaan K210 riscv
configs, as they all use uclibc flat binary format which disabled
libatomic:

Fix this by modifying package/gcc/gcc-final/gcc-final.mk to add
libatomic to GCC_FINAL_LIBS only for configurations that have
BR2_TOOLCHAIN_HAS_LIBATOMIC set to "y".
