Lustre devel - Jul 2007 - [Bug 12842] Module symbol versions broken with external ldiskfs

The issue is that Module.symvers does not contain symbols for the external
ldiskfs module, so they are not read when performing ''modpost''
on fsfilt_ldiskfs.

As a workaround, I will add a rule to run modpost explicitly when building
fsfilt_ldiskfs.  This is required on RHEL 4, SLES 9, and RHEL 5.  The kernel
Makefile for 2.6.18 vanilla and SLES 10 can handle this situation more cleanly,
but running modpost explicitly will work for those kernels as well.
