For what it's worth, we use linker scripts (specified by the user, but
by-and-large provided by us; the user is welcome to create
board-specific linker scripts, of course) to handle most of the bits
that the -m<board> options currently handle.  (Libraries and linker
scripts bits seem to be all that -m<board> is used for anyway, and
linker scripts can fill in for both.)
