From: Eric Sunshine <[email protected]>
On PowerPC Mac OS X (10.5.8 "Leopard" with Xcode 3.1),
system header /usr/include/ppc/param.h[1] pollutes the
preprocessor namespace with a macro generically named MASK.
This conflicts with the same-named macro in ewah/bitmap.c.
We can avoid this conflict by using a more specific name.

git-compat-util.h ->
sys/sysctl.h ->
sys/ucred.h ->
sys/param.h ->
machine/param.h ->
ppc/param.h
