i think you're trying too hard.  you're trying to combine three targets at 
once: the host system (ppc), the build system (i686 prob), and canadian cross 
for some other random build system (mingw).

the logical step would be to only build the tools for your random other build 
system instead of trying to combine it all together.  in other words, set the 
HOSTCC to your mingw compiler and only process the tools target.  this is how 
every other package out there works and it doesnt really make sense to have u-
boot be different in this regard.
