Subject: [PATCH] LU-6790 build: handle external Intel OFED stack

Besides the Mellanox stack Intel also releases their own
OFED stack. Just like the Mellanox stack this Intel OFED
stack has a compatibility layer to support distributions
kernels. This layer provided stomps over the default
kernel headers so like the Mellanox stack compact-2.6.h
has to be placed before all other headers. The reason
it didn't show up before with the Mellanox stacks is the
Intel stack additionally stomps the pci layer of the
kernel.
