Some makefile modifications to:
>>disable the logic that detects and sets architecture (it screws up cross-compiling)
>>disable some secondary build functions like creating changelogs or report files for other tools
>>disable the install functionality as we take the files we need with OpenWrt build system
>>changes to all makefiles to respect the compile flags
