I recently merged the latest upstream changes into our fork of clang and
noticed that clang now ignores the -target flag if it is invoked as
*-*-*-clang:

./mips64-unknown-freebsd-clang -target x86_64-unknown-freebsd -### foo.c
clang version 6.0.0 (https://github.com/llvm-mirror/clang.git
e7476fadc94b87293e7192c419125cf446d454ce)

I would expect this to target x86_64 and not mips64.
