It also includes patches for various software packages - mainly the ones -involved in the cross-compilation tool chain (+gcc+, +binutils+ and +involved in the cross-compilation toolchain (+gcc+, +binutils+ and +uClibc+). There is basically one Makefile per software package, and they are -named with the +.mk+ extension. Makefiles are split into three main -sections: +named with the +.mk+ extension.
