Enable Lustre to be built with OFED 1.4.1.

This is just the glue needed for the build with OFED 1.4.1 to actually work.
OFED 1.4.1 won't actually get built with a Lustre branch until a target file
specifies:

OFED_VERSION=1.4.1-rc4

Note that OFED 1.4.1 only supports RHEL4, RHEL5 and SLES10 targets.  SLES9
users are out of luck (but have been for some time with OFED).
