Some of the recently added tests are not compatible with GCC. Also checked compatibility with GCC 10
If the compilation fails, the test is marked as unsupported.
-> This will never change for a specific version of gcc
If the linking fails, the test is marked as expected to fail.
-> This might change as LLVM/OpenMP implements the missing GOMP interface function
I successfully ran make check-libomp with GCC versions 6-10
Issues with the OMPT tests are addressed in D82267
