New Revision: 170016

URL: http://llvm.org/viewvc/llvm-project?rev=170016&view=rev
Log:
The ordering of two relocations on the same instruction is apparently not
predictable when compiled on at least one non-PowerPC host.  Source of
nondeterminism not apparent.  Restrict the test to build on PowerPC hosts
for now while looking into the issue further.
