description:
Don't special case aarch64 and add -fomit-frame-pointer to builds.

This behaviour is probably due to a past behaviour of clang, where it
always emitted frame pointer code.
This is no longer true for clang on netbsd, and I don't think it was true
for GCC.

Meanwhile, this flag bleeds into pkgsrc where it breaks random packages,
requiring workarounds like lang/ruby*-base/hacks.mk.
