configure --target=powerpc-eabi

You need to first build and install binutils, gas and ld. Then
configure & build gcc+gdb.

See http://sourceware.cygnus.com/ecos/install-linux.html for more
details. And note that if you have recent sources you may not have to
download the eCosSWtools.


For eCos you don't need newlib. There's a separate libc implementation
for eCos.

And use -mcpu=860 in CFLAGS when building stuff.  The existing eCos
platforms already use this option.
