RFR(xs): 8171225: [aix] Build gtests on AIX 7.1 with xlC 12

[Volker Simonis]

Hi Thomas,

can you please try to fix the TOC issues for the gtest build only. I
don't like that we have to build everything with '-qpic=large
-bbigtoc' just because of gtest.

Isn't it possible to just set these parameters in
hotspot/make/lib/CompileGtest.gmk by using CFLAGS_aix/LDFALGS_aix?

Thanks,
Volker
