Is there a standard for multiarch library path locations and names?
Multiarch seems to be a debian/ubuntu creation. Debian and ubuntu seem
to be consistent at least on i386 and amd64. I'm not sure what the
situation is with arm ports of ubuntu (note that multiarch triplets are
supposed to represent an ABI so two arm ports with incompatible ABIs are
supposed to have different multiarch triplets).
If not, that sounds like configuration option that should be added by distribution-specific patches.
I've attatched a patch to debian/rules to add the multiarch path to the
configuration installed by the debian package.
