When running the valgrind tests, the jm-insns test is segfaulting when it

attempts to patch instructions as it deals with the ppc64 (BE) function
descriptor. This is actually due to the RELRO option being enabled by default
for the ppc64 (BE) platform, per an upstream binutils change.

Bugzilla 365912 reported by  Will Schmidt, Will supplied the patch to fix the
make file none/tests/ppc64/Makefile.a

Patch tested on Power 7 and Power 8.
