Steps to reproduce the problem:
1. ./chromium/scripts/build_ffmpeg.py linux mips64el

What is the expected behavior?
build success and generate config.h file.

What went wrong?
clang is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
