maybe we should:
- keep emulation binary detection part even if we don't have
- on program invocation, exclude every obviously-non-netbsd binaries,
- execute as netbsd binary if none matches.
i think this is kinda ugly, but i'm not sure how else to do it. PR#12253 is
certainly fairly compelling, though of course on needs to be root to do this
and therefore can be put down to "user error" (but the failure mode is damn
but certainly the solution that simply refuses to run correct programs
because they don't have a tag is no good. it makes it impossible (sans a
kernel rebuild) to run programs that are otherwise completely useful.
the thing is that while one generally should use our crt* when linking, it
isn't always necessary or applicable. in a pure-assembly program why
should i have to create a special .note section? espcially one that isn't
well documented outside of the NetBSD source code.
the current situation seems "anti-embedded" to me.
