Fixes issue https://github.com/OP-TEE/optee_os/issues/179 (GNU make 4.0
rebuilds everything each time it is run).
GNU make 4.0 includes a fix for bug http://savannah.gnu.org/bugs/?16051
which breaks the C compilation rule in mk/compile.mk. Previous versions
of make would not add the FORCE target to $?, whereas version 4.0 does.
Therefore, one must explicitly exclude FORCE from $? to properly detect
if dependencies have changed.
