As far as I know, it should work. But I never tried that WinCE stuff,
so don't rely on me here.

The "bootstrap" does not make any sense here. You cannot bootstrap a
cross compiler by principle.  A simple "make" is sufficient.

						    ^^

Do you have built cross platform binutils? You need them for a cross
compiler.

What is the output of the failing command with a "-v" added?
