No it doesn't.  If it did, you wouldn't be adopting dolt.
OK, you put "works" in quotes, so I guess that's what you meant.

Even posting the sed hacks or the diffs against 1.5.10 that you were
using (both to libtool-patches, please) are better than nothing.

Proper sysroot support in Libtool would be very welcome, but
unfortunately it won't be easy.  Of course there are more constraints:
it should work right in most practical cases, not just the ones your
package cares about.  Since it cannot be made to work on some systems
due to linker and binary file format limitations, it should degrade
gracefully on those systems.

I've tried it a couple of years ago, but gave up since I figured it
would take me all remaining weekends of the year to do.

Cheers,
Ralf
