FYI: I am not talking about using "make -C <dir>", which probably
is much faster on M$ hosts than RTEMS's implementation, but about
removing --enable-gmake-print support and to apply a variant of
automake's subdirectory.
Automake's subdirectory rule seems to be a little bit faster, but I
wouldn't bet on this.
Attached to this mail is my proposal.
After applying the patch, please run
cvs rm aclocal/enable-gmake-print.m4
./autogen
