[8u] RFR (S) 8175813: PPC64: "mbind: Invalid argument" when -XX:+UseNUMA is used

[Gustavo Romero]

Hi,

Could this backport of 8175813 for jdk8u be reviewed, please?

It applies cleanly to jdk8u except for a chunk in os::Linux::libnuma_init(), but
it's just due to an indentation change introduced with cleanup [1].

It improves JVM NUMA node detection on PPC64.

Currently there is no Linux distros that package only libnuma v1, so libnuma API
v2 used in that change is always available.
