      build: rework library bundling · 72d751cb
      Jo-Philipp Wich authored 
      

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.

      sdk: stop shipping a .config · 9eeb267c
      Jo-Philipp Wich authored 
      

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can stop shipping a (possibly outdated) copy of .config from the emitting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

      sdk: predefine kernel version magic · 057e5182
      Jo-Philipp Wich authored 
      

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.
