commit: https://git.buildroot.net/buildroot/commit/?id=f88bf61b2934c00aeff12346c2d7dc45b9ab9cda
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

On some architectures, atomic binutils are provided by the libatomic
library from gcc. Linking with libatomic is therefore necessary,
otherwise the build fails with:

sparc-buildroot-linux-uclibc/sysroot/lib/libatomic.so.1: error adding symbols: DSO missing from command line

This is often for example the case on sparcv8 32 bit.

Fixes:
