I'm not a gcc expert so I don't know.  It would be ideal if gcc could
tell you the subdirectory for a given set of flags (instead of trying
to parse -print-multi-lib output) and then copy only those libraries.
Include files would need to be copied separately of course.  Then
you'd either need a symlink in the target directory so that gcc
doesn't get confused, or a flag to tell gcc to turn off multilib.

You might try asking Segher Boessenkool (cc'd).  He's quite adept at gcc-fu.
