Jo-Philipp Wich ef1cafa736 build: fix invocation of bundled ld.so in SDK and Imagebuilder 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.

README

This is the buildsystem for the LEDE Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
