A few HWCAP entries are missing from aarch64/cpuinfo.c. This results in build
errors
on older machines.
This counts a trivial build fix, but since it's late in stage 4 I'll let
maintainers chip in.
OK for commit?
libgcc/
* config/aarch64/cpuinfo.c: Add HWCAP_EVTSTRM, HWCAP_CRC32,
HWCAP_CPUID,
HWCAP_PACA and HWCAP_PACG.
