I don't know why, but lines 21-27 of configure.in read
something like this:

     21  # Gets build, host, target, *_vendor, *_cpu, *_os, etc.
     22  # AC 2.5x sets target_alias iff the user specified --target, 
but we use
it
     23  # everywhere, so we set it here just to be sure.  In AC 2.13
     24  # AC_CANONICAL_TARGET was known as AC_CANONICAL_SYSTEM.
     25  AC_CANONICAL_SYSTEM
     26  target_alias=${target_alias-$target}
     27  AC_SUBST(target_alias)

This could be the source of the problem - the GCC configure
scripts merely call AC_CANONICAL_SYSTEM and continue.

I'm not too familiar with autoconf/automake so this could be
way off target (no pun intended!).
