[Werner Almesberger <werner@...>]

With this small change, we can use "make -j", which considerably
improves compile time on multicores.

GNU Make's logic for recursive makes is a little twisted: if it
sees a $(MAKE) in a rule, it knows that this is a recursive make
and implicitly passes -j. This happens only before expaning the
rule. That's why it doesn't see the $(MAKE) inside $(MAKEGTK).

The "+" is a mechanism to explicitly tell GNU Make that there's
a recursive make.

This patch depends on dont-hide-make-failure.patch
