Subject[PATCH 04/16] net: bpfilter: use 'userprogs' syntax to build bpfilter_umh
Date
The user mode helper should be compiled for the same architecture as
the kernel.

This Makefile reuses the 'hostprogs' syntax by overriding HOSTCC with CC.

Now that Kbuild provides the syntax 'userprogs', use it to fix the
Makefile mess.
