Commit 72d751cba9 "build: rework library bundling" introduced a new helper
binary "runas" whose sole purpose was mangling the argv vector passed to
the actual called ELF image so that the renamed executable could obtain the
proper name from argv[0].
This approach, however totally defeated the purpose of calling bundled ELF
executables through the shipped ld.so loader since the execv() invocation
performed by "runas" would cause the kernel the interprete the final program
image through the system ELF loader again.
To solve the problem, use an alternative approach of shipping a shared object
"runas.so" which uses an ELF ".init_array" function pointer to obtain the
argv[] vector of the to-be-executed main() function and mangle it in-place.
The actual argv[0] value to use is communicated out-of-band using an
environment variable "RUNAS_ARG0" by the shell wrapper script. The wrapper
script also takes care of setting LD_PRELOAD to instruct the shipped ELF
loader to preload the actual ELF program image with the "runas.so" helper
library.
Fixes FS#909.

The feeds script sets value of TOPDIR in a way that is inconsistent
with how toplevel Makefile sets it. The inconsistency manifests when I
use a "build directory" with symlinks to LEDE source (see below).
When make is invoked in such a directory, make's TOPDIR variable is
set to that directory, whereas scripts/feeds sets TOPDIR to the top of
LEDE source, which results in creating feeds directory inside the LEDE
source instead of in the build directory.
This patch changes the script so that it reuses the TOPDIR value form
the environment if it exists. The result is that 'make
package/symlinks' correctly fetches feeds to the build directory
instead in the source.
I use the following commands to create the build directory:
ln -s $SRC/config config
ln -s $SRC/Config.in Config.in
ln -s $SRC/feeds.conf.default feeds.conf.default
ln -s $SRC/include include
ln -s $SRC/Makefile Makefile
mkdir package
ln -s $SRC/package/base-files package/base-files
ln -s $SRC/package/boot package/boot
ln -s $SRC/package/devel package/devel
ln -s $SRC/package/firmware package/firmware
ln -s $SRC/package/kernel package/kernel
ln -s $SRC/package/libs package/libs
ln -s $SRC/package/Makefile package/Makefile
ln -s $SRC/package/network package/network
ln -s $SRC/package/system package/system
ln -s $SRC/package/utils package/utils
ln -s $SRC/rules.mk rules.mk
ln -s $SRC/scripts scripts
ln -s $SRC/target target
ln -s $SRC/toolchain toolchain
ln -s $SRC/tools tools
This allows me to easily test changes in LEDE on multiple targets.

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 external script used to generate the package lists for the
LEDE wiki's table of packages [1] and package indexes [2] requires
a "Source:" field in the package lists to find package makefiles.
The package makefiles are used to read the package's Category and Submenu.
The "Source:" field was removed in commit
b4aa3c899c
to reduce package list sizes and lessen opkg issues in low ram devices.
Add a separate package list file with full data to be used by the wiki's script.
It's called Packages.manifest and isn't compressed as it's not necessary.
