Idea from Phil to have a portable method to find
the kernel module dependencies. make-module-ipkgs.sh
uses associative arrays, so check for bash version 4.

The new prereq check is completely implemented in
POSIX shell in scripts/prereq.sh.
It combines the old features from Makefile, scan-tools.sh,
scan-pkgs.sh, reloc.sh and some wrappers for tools.
The big benefit is to have all portability stuff in one place.
Furthermore we can compile GNU make and bash on the fly, for
systems lacking the required tools.
All changes on the host are detected on the fly, no make
prereq required anymore.
The build process is separated in following three phases:
1. small wrapper Makefile is used for BSD make or GNU make
2. prereq.sh is called, doing all checking, calling Makefile.adk
3. old logic in Makefile.adk or mk/build.mk is used
Tested successfully on Linux, MacOS X, Cygwin, FreeBSD, OpenBSD
and NetBSD.
An old depmaker bug was fixed, only optional host tools are compiled.
For example, even when a host provides xz, a local xz was compiled
in the past, because other packages had a build dependency on it.

We need it for toolchain components.
Add latest config.sub/config.guess from upstream
with a minor patch for sh2eb detection.

The recursive call of find_modlevel overwrites the loop variable 'dep'
if not declared local before. Yay.

Instead of maintaining mk/modules.mk which defines compilations of
related kernel modules to pack together into a single package, follow an
automatic approach: For every kernel module found in the modules
installation directory, create a single package.
There are a few caveats to cover:
=== Module Loading Order ===
Upon bootup, module loading is ordered based on the number-prefixed
files in /etc/modules.d/. The correct number was previously managed in
mk/modules.mk on a per-collection basis. The new approach is to have
levels which modules are to be assigned to. Level 0 contains modules
with no dependencies at all. Level 1 contains modules which have only
level 0 dependencies, and so on. This information is determined at
compile-time by make-module-ipkgs.sh.
=== Module Installation to Target RootFS ===
Since module packages are created automatically from the modules the
script finds, ADK build system has no knowledge about the connection
between what the user has selected in menuconfig and the actual module
packages. Therefore the earlier approach to install selected packages
into rootfs does not hold anymore. Instead, use wildcards to find all
packages in firmware directory prefixed by 'kmod-' and install them all
(hopefully doing the right thing).
=== Kernel Version ===
KERNEL_VERSION now contains KERNEL_RELEASE already
By creating a localversion file, make KERNEL_RELEASE part of the
kernel's version number (so KERNEL_VERSION is correct in most
situations)

We don't need this, as ARCH is implicit through the directory.
All lower case symbols should be removed now.

Keep the option filtering as it actually prevents lots of package
patching.
