This seems like a larger problem, not something OpenMP specific. Perhaps
Clang should add it's installation-prefix include directory to its list
of system include paths? Alternatively, or in addition, we should make
sure that omp.h is installed into Clang's lib/include directory along
with other compiler-specific headers.
