Boot stuff dependencies from NetBSD. Patch by Antoine Leca. Relocated to src/sys. The port is using the same libminc.a as usual MINIX services (and does not use NetBSD libkern); the headers imported from NetBSD sys/ tree have been kept to a minimum (still numbers higher than 30 though.) Note the peculiar way to use libraries (libsa, libi386, etc.): the source code is shared, but each component builds its own copy of the library, with its own set of preprocessor defines.
