powerpc: Add space for HWCAP3/HWCAP4 in the TCB for future Power.
This patch reserves space for HWCAP3/HWCAP4 in the TCB of powerpc.
These hardware capabilities bits will be used by future Power
architectures.
Versioned symbol '__parse_hwcap_3_4_and_convert_at_platform' advertises
the availability of the new HWCAP3/HWCAP4 data in the TCB.
This is an ABI change for GLIBC 2.39.
