I actually don't like this that much, because I like a lot the fact
that I can do "make <foo>-source" "make <foo>-extract", "make
<foo>-patch" or even "make <foo>" (though this last case, for the
specific situation of uClibc doesn't seem really possible).

Though it's true it can be considered a bit strange to allow "make
<foo>-patch" but not "make <foo>-menuconfig".
