On x86_64-apple-darwin15, I see two additional failures with gcc 6.0svn..

Testing for "omp_get_wtick":
Generating sources .............. success
Compiling soures ................ success
Running test with 8 threads ..... failed 100% of the tests
+ orphaned mode:
Generating sources .............. success
Compiling soures ................ success
Running test with 8 threads ..... failed 100% of the tests

and 17 less tests being verified compared to clang 3.8svn.
