Fair enough, I'll have to look into what our options are. I think the libtool mismatch issues are likely why we've not looked into this autoreconf. I know we have problems with libtool in both binutils and gcc which mean we have heavy patches for that.

GCC is using a 2009 version of libtool (reportedly commit > 2c9c38d8a12eb0a2ce7fe9c3862523026c3d5622) with lots of local patches, some > of which may not be upstream (libtool upstream isn't very active), and > different interpretations of --with-sysroot mean that updating libtool in > GCC would also require reverting libtool commit > 3334f7ed5851ef1e96b052f2984c4acdbf39e20c in the new version of the libtool > files used in GCC (in addition to making sure that any other > not-yet-upstream local libtool patches are preserved).
I think this is the key part of the problem, we carry a patch to rename the option in libtool due to the conflicts the libtool naming caused.
We do have a queue of libtool patches, I'd love to see a way of reconciling the sysroot option issue with libtool upstream. Its a chicken and egg problem since we're less likely to spend time on sending the patches if we aren't likely to see them at least get into source control. I guess I'm diverging for the autoconf list now though!
Cheers,
Richard
