Subject: Attempt to fix clang-cmake-mips after r268977.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=14086eae46a26c5d75d7712ea677e4b49e17546b;p=platform%2Fupstream%2Fllvm.git

Attempt to fix clang-cmake-mips after r268977.

I think it's wiped out the build area and fully-reconfigured for the first time
since r268977. This seems to have caused Mips64 to become enabled when it wasn't
before because compiling with -mabi=64 succeeds but linking with -mabi=64 fails.
