So this one is more involved, see the two patches below, the first fixes
the clang command option probing mechanism used and the second filters
out -ffat-lto-objects.

Its all in my tmp.perf/urgent branch at
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git.

The full test suite is still running, but so far the failures are
unrelated to the problems in this thread:
