New Revision: 136644

URL: http://llvm.org/viewvc/llvm-project?rev=136644&view=rev
Log:
Driver: When compiling i386 -fapple-kext code, we fallback to llvmgcc.
Unfortunately, llvmgcc doesn't always work when writing temporary output to
/dev/null.  Therefore, create a temp file that is later deleted.
