Rework the bundle-libraries.sh implementation to use a more robust approach
for executing host binaries through the shipped ELF loader and libraries.
The previous approach relied on symlinks pointing to a wrapper script which
caused various issues, especially with multicall binaries as the original
argv[0] name was not preserved through the ld.so invocation. Another down-
side was the fact that the actual binaries got moved into another directory
which caused executables to fail looking up resources with paths relative
to the executable location.
The new library wrapper implements the following improvements:
- Instead of symlinks pointing to a common wrapper, each ELF executable
is now replaced by a unqiue shell script which retains the original
program name getting called
- Instead of letting ld.so invoke the ELF executable directly, launch
the final ELF binary through a helper program which fixes up the argv[0]
argument for the target program
- Support sharing a common location for the bundled libraries instead of
having one copy in each directory containing wrapped binaries
Finally modify the SDK build to wrap the staging_dir and toolchain binaries
which allows to use the SDK on systems with a different glibc version.

The SDK Makefile still trys to copy the docs folder which was removed
with 882f4d2d63. This causes an SDK build
error.
All other removals are just cleanup.

When building packages within the SDK, there is no Git revision history
available so prepopulate SOURCE_DATE_EPOCH in version.mk, similar to
how we handle REVISION already.

With symlink tree some directories are just symlinked which
means IB and SDK end up with a symlink instead of an actual
directory; this fixes the missing files by dereferencesing
the directories instead of copying the symlinks.

The configuration preservation mechanism fails to keep items was are unset
as unset. For busybox this causes issues when building with custom
settings in the SDK. Therefore preserve busybox unset settings.
In addition we preserve non-package selection unset settings because
they may be important for making sure we compile and identical
package for packages that are recompiled in the SDK.
Now that SDK not longer ships .config this becomes relevant for
any use of the SDK.

Commit d79f8909c1 introduced CONFIG_ALL,
CONFIG_ALL_KMODS and CONFIG_ALL_NONSHARED as menuconfig choices to the SDK,
therefor we can drop the hardcoded CONFIG_ALL symbol declaration now.

Now that the most important options are exposed via menuconfig in the SDK we
can stop shipping a (possibly outdated) copy of .config from the emitting
buildroot.
Leaving out .config has two positive side effects:
- A simple "make" run without any prior config will launch menuconfig, forcing
interactive users to make appropriate choices
- Buildbot systems (e.g. our phase2 builder) can issue a "make defconfig" to
obtain a .config enabling all packages by default

It is desirable to be able to use ./scripts/feeds install -a
when in the SDK without being forced to build a great number
of packages that are not actually wanted.
We therefore add the option of changing the various ALL package
build options so that we can default to packages not being built
unless we select them.

Initialize a Git repository in the SDK and use git reset / git clean
to rollback any SDK changes with "make clean" or "make dirclean".
This approach is more robust than nuking entire directory trees because
some parts of them might have been shipped with the original archive.

Kernel modules which are built using the SDK do not have access
to the .vermagic file in the Linux build dir, therefore the
generated .ipk metadata depends on kernel versions like
'3.10.49-1-unknown' which are not satisfiable by the kernel
meta package in the image.
Fix this problem by substituting 'unknown' with the current
version magic in include/kernel.mk when packing the SDK.
