Stefan Pintilie a614a28772 [PowerPC] Do not define __PRIVILEGED__
We do not want to define __PRIVILEGED__. There is no use case for the

Jake Egan 3b39fa3e28 [AIX] Define __HOS_AIX__ macro only for AIX target
%%%
This patch defines the macro __HOS_AIX__ when the target is AIX and without any dependency on the host. The macro indicates that the host is AIX. Defining the macro will help minimize porting pain for existing code compiled with xlc/xlC. xlC never shipped cross-compiling support, so the difference is not observable anyway.

Jake Egan 41bcfe8174 [AIX] Define _ARCH_PPC64 macro for 32-bit
%%%
The macro _ARCH_PPC64 is already defined for 64-bit, but this patch defines it for 32-bit on AIX to follow xlc. See: https://www.ibm.com/docs/en/xl-c-and-cpp-aix/13.1.0?topic=features-macros-related-architecture-settings

Note: This change creates a discrepancy between GCC, which defines _ARCH_PPC64 only for 64-bit mode.

GCC's definition for 128-bit float types on PPC, so macros/functions in
