--- Comment #4 from nsz at gcc dot gnu.org ---
this might be a different issue, but then i'm not sure how you made the gcc
build to use the alternate glibc path.

can you attach the libatomic/testsuite/Makefile (with the CC etc variables
set)?

i think the atomic tests should work without -pthread and i think libgomp just
happens to pass because -fopenmp implies -pthread.
