[uClibc] Cross compile toolchain

[Earl Chew]

I'm trying to build a powerpc toolchain hosted on cygwin.

The build failed with the message:

mv: `Tcollect2' and `collect2' are the same file

It took me a little while to figure out that the toolchain makefile
assumes a linux pc host, whereas I need to specify i686-pc-cygwin.

I'm surprised that the build got as far as it did!

On cygwin, gcc -dumpmachine yields the correct content (i686-pc-cygwin)
for the host compiler specification.

Would the following patch allow the GNU_HOST_NAME to be correctly
determined?
