yup. it might well be OK to have a small portability library that
copes with some of the more commonplace non-standard functions
(e.g. err/warn), just as e.g. the toolchain has libiberty. however,
it should be fairly obvious how to bootstrap the whole thing, and
requiring a zoularis-like environment is just Too Much.
I actually think there are probably plenty of assumptions that you
could make to make your life easier, too. (e.g. ANSI C.)

right. unfortunately, there's more than there might otherwise be
because some of our necessary basic tools, e.g. config, need lex and
yacc, but so be it.
among the usual suspects for netbsd are make, config, and i dunno

Yes, if there are things missing for other hosts, they should be added
back. And, as important, we need to be getting our changes back into
the GNU distributions of the tools.

I'd actually say that a shell script is in order, rather than anything
else. (There's no real notion of 'targets' an 'dependencies,' just
everything to do and the right order to do it in. 8-) Avoids a lot of
hassle that way.
