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.

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
