I'm not saying it is terribly useful, just that it differs from -L. I'm
not sure how the 32bit compat libraries are build on FreeBSD. For
NetBSD, we change the default SEARCH_DIR entries in the linker scripts.
For native binary format, it uses =/usr/lib, but for the -m32 equivalent
on amd64, it uses =/usr/lib/i386. That means all the search logic is
isolated in the linker script and no further command line changes are
necessary.
