[Bug 54940] Import library generation is much slower without dlltool

--- Comment #3 from Zeb Figura  ---
This definitely has made iterative development slower for me.

Anyway, I can think of at least two possible solutions for this:

* Fix GNU dlltool, and allow using the system dlltool if it works correctly.

* Take our cues from GNU dlltool, and (optionally) link directly to libbfd in
order to create a single archive with separate sections. This would require
making winebuild GPL3, but according to my understanding that doesn't mean that
Wine itself needs to be GPL3.
