Subject: Try to run and investigate the mips-mti-linux.c test failure on ARM buildbots.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6d07a67d27753c3c3f08ceec87edc6620d7b7698;p=clang

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.
