Hi Joseph, hi Jakub,

Lightly tested draft patch attached. (--enable-autolink-libatomic is 'no' by default)
Does this make sense, in principle?

When trying the patch, one runs into the problem that -latomic
fails in the target configure for libgomp ("error: C compiler
cannot create executables"). Any suggestion? (That's on x86_64-gnu-linux.)

(b) I start thinking that putting it into libgomp.spec – possibly with the new configure
--enable... flag and/or only for nvptx (which uses libatomic via
../libgomp/config/nvptx/atomic.c) – is the better solution.
Thoughts?
