. make vm tell kernel virtual locations of mappings
. makes _minix_kerninfo feature work
. fix for mappings being larger than what 1 pde can address
(e.g. devices memory requested on arm)
. still requires a special case for devices memory for the
kernel, which has to switch to virtual addressing

Small GPIO driver that exports a few pins using a virtual file
system. Currently the two user leds and the user button are exported.

- Do not run the fetch.sh script every time
- Do not run the configure script with MKUPDATE=yes (build.sh -u)
- The fetched GNU source are hidden from `git status`
- With CLEANFETCHED=yes, `nbmake -C tools cleandir` will remove the
fetched GNU source and return the MINIX tree to its pristine state.
- Avoid (harmless) message when building in parallel, about find
running against an inexistant path
Notice that the GNU tools are "installed" on every run, even with
MKUPDATE=yes; this is a feature of the NetBSD build system, because
in case of changes in dependencies it is impossible to know them.
See commit 1.27 2004-06-12 of tools/Makefile.gnuhost in NetBSD's src/
The downloaded tarballs are not removed with CLEANFETCHED:
they are supposed to be unmodified, and the exact name is not known
to the Makefile's, since it is engraved in each fetch.sh script (and
we do not want to have the same information in several places.)
On ARM we can't yet globally map pages into every process. So now that
we correctly receive the pointer to the globally mapped kern_info
struct, we have to ignore it on ARM because attempting to dereference
the pointer yields a segfault.
So we don't have to figure out which line generated this error by
searching for the subtest/error code combination.

Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.
There is also a few related Makefile updates as well as minor
source code corrections.
The value was changed to no for cross-building as the old binutils
could not handle the required flag. As this is now possible, the
default is restored.
This flags make sure that AR zeroes out some timestamps and uid/gid
fields in libraries, which would change for every build of the
library otherwise, preventing comparison between to builds.
