S390X and PPC64 architectures detection is wrong

[Tomas Popela]

After the https://bugs.webkit.org/show_bug.cgi?id=156015 was committed it showed that the PPC64 detection is wrong as on the CPU(PPC) path was activated even for PPC64. The thing is that GCC defines __ppc__ even on PPC64 and not just on PPC(32). The same applies for S390X.

$  gcc -dM -E - < /dev/null | grep PPC
#define _ARCH_PPCGR 1
#define __PPC64__ 1   <---
#define _ARCH_PPCSQ 1
#define _ARCH_PPC 1
#define __PPC__ 1     <---
#define _ARCH_PPC64 1

Please, use the revision number here instead of (or in addition to) the bug. I usually grep rev numbers to see commits fixing regressions introduced in other commits, or follow ups, etc. It makes my life easier :-)
