We are using AM_LDFLAGS to pass -libverbs parameter in the Makefile.
You can find this Makefile under OFED-1.1-rc5/SOURCES/openib-1.1 (just
open openib-1.1.tgz)
See an example:
libmthca: libibverbs
        $(MAKE) -C $(SRC)userspace/libmthca \
        AM_LDFLAGS="-L../libibverbs/src -libverbs"
        @echo "Make libmthca done"

libipathverbs: libibverbs
        $(MAKE) -C $(SRC)userspace/libipathverbs \
        AM_LDFLAGS="-L../libibverbs/src -libverbs"
        @echo "Make libipathverbs done"

libehca: libibverbs
        $(MAKE) -C $(SRC)userspace/libehca \
        AM_LDFLAGS="-L../libibverbs/src -libverbs"
        @echo "Make libehca done"

Exactly. Using this way we enable OFED RPMs building without affecting the
running environment.
