Fix broken build due to new OMPT tests

[hbae]

Summary

New OMPT tests with teams construct should be disabled for GCC.

[jdoerfert]

Could you elaborate why (I mostly interested)?

[hbae]

GCC emits code with a GOMP* entry that is not supported in the LLVM runtime.

[jdoerfert]

Sounds like a valid reason to me. Thx.
