You need the OS part of the config tuple.  If ./config.guess says for
instance athlon-pc-mingw32msvc then use none-pc-mingw32msvc.  There's
a note about this in the manual.

"i386-whatever-whatever" is a good choice for code to run on a variety
of x86s.

Not currently, but we will update configure and libtool in the next
release, which should allow it.
