[11u] RFR: JDK-8255734: VM should ignore SIGXFSZ on ppc64, s390 too

[Thomas Stüfe]

Hi,

may I have reviews please for the following backport:

Original issue: https://bugs.openjdk.java.net/browse/JDK-8255734
Original patch: https://github.com/openjdk/jdk/commit/54c88132.diff
Modified patch:
http://cr.openjdk.java.net/~stuefe/webrevs/backports/8255734-VM-should-ignore-SIGXFSZ-on-ppc64-s390-too.diff

Patch is trivial and nothing changed, but did not apply correctly since
"8252324: Signal related code should be shared among POSIX platforms"
shuffled a lot of coding around.

Thanks, Thomas
