arm64 yes, mips64 no, see below.

I don't know about the binutils strip implementation. But I believe
you can build it to support multiple targets. You might want to ask on
the binutils list.

Normally elfutils is build with all supported backends, so yes.

Without a mips64 backend you cannot trust it. Debian apparently has a
mips64 backend but it isn't upstreamed.  See also: And:
