ouch...

for Windows, developers need to download GNU make anyway, and i don't
think it's a problem if we require a Win32 GNU make >= 4.0... i don't
have the time and inclination to support non-Win32 GNU make anyway :)

but for the other platforms usually only GNU make 3.82 or even 3.81 (on
Mac, iirc) is available on the system, so if we require >= 4.0 then that
means another thing that has to be installed manually, which is probably
not a good direction to go in...

(and yes, i'm also unhappy about the needlessly ugly and inefficient
directory dependencies in gbuild to keep GNU make 3.81 support alive)
