Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

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
