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:
