Thanks for this patch, it made the $arch-host_unknown-linux-gnu-ar error 
go away when building a toolchain for x86_64 on i386. I came across 
another error when building for x86_x64:

 error: #error "glibc cannot be compiled without optimization"

Robert P.J. Day posted a patch in 
http://sourceware.org/ml/crossgcc/2007-05/msg00075.html, also patching 
crosstool.sh (is this the right thing to do?), so now we have:
