Hi Miloš,

  The GAS failure is due to the patch that suppresses TLBIE instruction checking.  (I forgot to check that the GAS testsuite did not test the instruction, and of course it does).  I will upload a simple patch that will
fix that problem.

  The LD failures however are a mystery.  I cannot reproduce them.  I assume
therefore that they must be an artefact of running the tests natively.  I
could create a patch to just mark those tests as expected failures, but I
would prefer to get to the bottom of the problem.  (I suspect that I just need
to add a line to regexp files to skip dumps of the .data section).  Is there a
RHEL 7.3 PPC64 machine available that I can use for testing ?

Cheers
  Nick

Fix PowerPC linker tests

With access to a PP64 machine (thanks Milos), I was able to reproduce the 
failures and find the cause - the native ppc tools always create a .data section
even if one is not needed.  This patch tweaks the failing linker tests to allow
for this fact.

Once we have a QA ACK, the two patches should go in.
