After some more thinking I think this would be a good idea:
- configure for each ISA to the same standard locations
   (e. g. bindir without $ISA suffix)
- install each ISA to a different, ISA-specific tree
- user-settable scripts allow merging of these trees
   verbatim, select specific binaries or move them to
   $ISA subdirs

I'll may have some time next week to prepare something.

The dependencies in gar.pkg.mk were too strict, so
your files got overwritten each time after install. This
should be fixed in r2023:
   <http://svn.blastwave.org/trac/changeset/2023>

I couldn't verify this although I copied your tree. Please
check again with r2023. If the error is still there I see
what I can do on your tree directly.
