That's why I wrote up a few howto's in the past, and the latest one is
cygwin->linux. See http://www.nanotech.wisc.edu/~khan/software/gnu-win32/
for details.
The trouble, as you've found out, is that various targets use different
gcc versions (or patches to it), and it gets trickier to build. The only
gcc that will build without tweaking is the gcc distributed by Cygwin
team, but that may not have some of the patches that your target may
require. And this is where the vendors for these embedded systems can
do a lot of good, but of course support costs real money. Then again, so
does time.

This is where debugging comes in. Here's what you do:
$ make all-gcc LANGUAGES="c" CFLAGS=-save-temps
and look at prefix.i file and see what gives. And then you'll get to the
next problem, and the same applies, and so on. Fun, isn't it?
