[PATCH] D51312: [OpenMP][NVPTX] Use appropriate _CALL_ELF macro when offloading

[Gheorghe-Teodor Bercea via Phabricator via cfe-commits]

When offloading to a device and using the powerpc64le version of the auxiliary 
triple, the _CALL_ELF macro is not set correctly to 2 resulting in the attempt 
to include a header that does not exist. This patch fixes this problem.
