Thanks for the reply.

So one cannot download gcc and binutils and follow the instructions for
building the cross-compiling tools then run use them to build NetBSD?

Don't use xscale-elf.  Use arm-netbsdelf.  You must use a toolchain=20
properly targeted to NetBSD.

If you want to enable the xscale optimizations in the compiler, all you=20
need to do is pass -mcpu=3Dxscale to arm--netbsdelf-gcc.

"" at the src toplevel should take care of building the=20
toolchain for you.
