cygwin-gcc 4.5.1-2 is now available for both arches without libiberty.a.

For a cygwin-target cross-compiler, binutils' ld/configure.tgt
hard-codes $(tooldir)/lib/w32api as an additional library directory.
While technically valid, is it not where we want libraries to be when
using a sysroot.

I added a small patch to binutils[1] to add sys-root/usr/lib/w32api and
have rebuilt cygwin-binutils and cygwin-w32api accordingly.

HTH,

P.S. I see that you already used this to fix the gcc-4.5 warnings in
winsup/cygwin, but you only applied those to your post-1.7.9 branch.
Any chance you could commit those to HEAD now as well?
