RFR (XXS): 8051378: AIX: Change "8030763: Validate global memory allocation" breaks the HotSpot build

[Volker Simonis]

Hi,

could somebody please review and sponsor the following tiny, AIX-only
change which fixes the HotSpot build on AIX for the 8u20/8u-dev code
lines:

http://cr.openjdk.java.net/~simonis/webrevs/8051378/
https://bugs.openjdk.java.net/browse/JDK-8051378

Details:

Unfortunately the merging of 8u11 into 8u-dev and 8u20 broke the
HotSpot build on AIX for those code lines.

The fix is trivial - just remove the unused function
os::set_error_file() in os_aix.cpp (as this has been done on the other
platforms by 8030763)

The webrev is against 8u20 but should apply equally well against 8u-dev.

Actually, it sould also apply against jdk8u/hs-dev/ and if that helps
it can also be pushed there first. That will in fact break the HotSpot
build on AIX in jdk8u/hs-dev/ until it will be synced up with the 8u11
changes, but I think that's not so important. It's much more important
to get the fix into 8u20 in time.

Thank you and best regards,
Volker
