Depending on GIT-CFLAGS would have a better chance of being safe, I
guess, even though it can at times be overly safe, than GIT-PREFIX,
I suspect.  As a single user target in Makefile, which is only used
by Dscho, who intends to stick to /mingw(32|64)/ convention til the
end of time, I think the posted patch is OK, though.
