Hello Bill,
It's looks like incorrect work of sys::IdentifyFileType() because it should be investigated ELF format instead of error message: "Incompatible object format!".
Nevertheless, MCJIT supports only x86 and ARM relocations, so these tests should be skipped in PPC as unsupported tests. Currently these tests have filter by targets_to_build, but correctly it should be filter by host native arch.
Attached the patch changed this filter.
But for builds with host_arch != target_arch and if we use configure/make instead of cmake it's can work incorrect because use target arch instead host arch.
So, this patch can be used as quick fix for this build: http://bb.pgr.jp/builders/clang-ppc-linux
But I'll work for provide host arch in Makefile and change the filter.
Regards,
Danil

Danil,
These seem to have broken the buildbots. Could you please investigate?
