[llvm-dev] sanitizer test case failures after OS update

[Don Hinton via llvm-dev]

Hi Bill:

Not sure if it was intentional, but the old builds set CC, CXX, and
LD_LIBRARY_PATH explicitly, but the new ones don't.  Also, you seem to be
linking against gcc 7.2 libs above, but building with gcc 6.4.1.
