Document new hard requirement on GNU make

As discussed in [1], it would be benificial for the GDB project to start
requiring GNU make to build its software.  It would allow using useful
GNU-specific constructs, such as pattern rules.  It would also allow
removing the alternative code paths in the Makefiles (guarded by
GMAKE_TRUE/GMAKE_FALSE), simplifying the Makefile code.
