Try to run and investigate the mips-mti-linux.c test failure on ARM buildbots. 

This should be a NFC for every toolchain other than mips-mti-linux (where we
print the list of directories searched for crt files). It will soon be
reverted once we hit the clang-cmake-armv7-a15-selfhost-neon buildbot.
