CONFIGURE: Speed up and get rid of little gnomes

Translated most of the engine work from shell to awk.

Tested that the output is the same (except the order of created files).

Time comparison
---------------
Windows:
* Little gnomes - 99s -> 0.3s
* Creating - 68s -> 1s
* Total - 205s -> 35s

Linux:
* Little gnomes - 3s -> 0.03s
* Creating - 2s -> 0.11s
* Total - 8s -> 3.8s
