>Description:
	Attempting to build the simplest program with clang and -g results
	in this under a powerpc64 installation:

	$ cat test.c
	int main(void) { return 0; }
	$ clang -g test.c
	/tmp/test-3U7Gsj.s: Assembler messages:
	/tmp/test-3U7Gsj.s:52: Error: unknown pseudo-op: `.cfi_sections'
	clang: error: assembler command failed with exit code 1 (use -v to see invocation)
        to debug other stuff
>How-To-Repeat:
	Use clang to build anything with -g under powerpc64.  Other
        architectures might be affected but I am not able to check.
