Very little. I wanted to wait to make sure immediate build system breakage from libgcc had been resolved; at this point, it has. I need to go back through this thread, revise the patch a little bit IIRC, and then post it for approval.

I'm going to be travelling all next week, so expect this around the last week of January.

Only a week late. I have lightly retested this on x86_64-pc-linux-gnu native; I am willing to do any specific testing requested. OK to commit, and what testing would you like to see first?

* Makefile.tpl (build_alias, host_alias, target_alias): Use
noncanonical equivalents.
* configure.in: Update AC_PREREQ.  Prevent error for AS_FOR_TARGET.
Set build_noncanonical, host_noncanonical, and target_noncanonical.
Use them.  Rewrite removal of configure arguments for autoconf
2.59.  Discard variable settings.
* Makefile.in: Regenerated.
