[openib-general] libibat/libibcm build mess

[Roland Dreier]

We probably want a patch like the below for libibcm.  I don't like it,
because it makes libibcm officially depend on libibat, but on the
other hand it's just making the current situation explicit.

Only this doesn't actually work: if we build libibcm after installing
libibat, the check for <infiniband/at.h> fails because at.h includes
sa.h, and libibat doesn't install sa.h.

 - R.
