- kernel-config.py replacement written in awk

- kernel-config.py replacement written in awk
- features:
-- pure awk, no need to BR: python, which may be problematic sometimes
-- over 40 times faster than python version (lacks value checking tho)
-- prints lots of useful warnings, like those:
    kernel-multiarch.config (2647): HW_RANDOM_VIRTIO=m should have explicit ` all='
    kernel-i386.config (60): CONFIG_NO_HZ already defined in: kernel-multiarch.config (103)

Changed files:
    kernel-config.awk -> 1.1
