Ok I see, I didn't know that pattern rules were GNU-specific.

As an honest follow-up question: do we need to stay compatible with
other makes than GNU make? From what I can see, Open/Net/FreeBSD all
use gmake to build their port of GDB already. I don't know about other
OSes on which people build GDB on (Windows, OS X, Solaris?). If GNU
make is readily available on these, perhaps we can consider making it a
requirement?
