        share/mk/sys.mk: revision 1.143

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.
