Can we take a step back here.  Did you regenerate the GCC and binutils
source trees with Libtool 2.4?  Upstream hasn't done that move yet,
precisely because the --with-sysroot issues need to be hashed out first.

Or are you trying to build GCC as well as other sources with the same
configure options?

Thanks,
