what <<< line? :-)

arm64 should be adde here, yes.  arm should remain -- it's
a fake netbsd32 in that it handles the old 32 bit ABI on
32 bit arm systems, so it's still useful.  we're not able
to support both that and EABI on arm64 currently (not sure
how it would be easy without making it possible to compile
the netbsd32 code twice, since there are additional layout
differences that are difficult to handle without letting
the compiler do it for you.)

sorry, i should have added arm64 here when i was looking
at it but i missed it.
