Synopsis: lang/ruby21-base fails to link due to undefined reference to 
`__atomic_compare_exchange_4'

Responsible-Changed-Why:
This is a more broad issue, we need to add support for all the
__sync* builtins for the C++ memory model
listed in /usr/src/external/gpl3/gcc/dist/gcc/sync-builtins.def
and treat them like we did with the __sync_* stuff (including a test
case and fixing all build breakage)
.
