cc-tool: pass -latomic in LIBS

Browse Source 
Just like -lpthread was passed in LIBS, -latomic should also be passed
in LIBS. In order for this to work, we however need to first fix
cc-tool's Makefile.am so that it does not overwrite LIBS.

This is the first part of fixing the build of cc-tool in a static
linking scenario on SPARC, i.e to fix:

  http://autobuild.buildroot.net/results/ed9f2524d0ccef318ff1bc99e5dea980111de989/

The patch has been merged upstream, in
553f9c6016.

Subject: [PATCH] Makefile.am: do not overwrite LIBS
LIBS is meant to be passed on the command line with additional
libraries, it should not be overwritten by Makefile.am.
Instead:
- Use LDADD to link with external libraries
- Use <target>_LDFLAGS for additional, non-libraries, linker flags
