I have build tested and ran 'make test' on both arm64 and riscv64. 
Nothing changes about riscv64.

arm64 -- M1

before:
= 97 failed, 44699 passed, 345 skipped, 2815 deselected, 33 xfailed, 4 
xpassed, 65 warnings in 525.39s (0:08:45) =

after:
= 97 failed, 44699 passed, 345 skipped, 2815 deselected, 33 xfailed, 4 
xpassed, 65 warnings in 509.20s (0:08:29) =

I'll see about zero initializing hwcap.
