These instructions are PowerPC assembly instructions, so the i686 as.exe
don't understand them.

If you want to cross-compile ppc code on cygwin running on windows for
another ppc machine, you have to make sure that you have a proper
cross-toolchain working on cygwin (compiler+binutils+...) to get
ppc code out of it.
