Finally used the discovered paths from ./configure in scripts/crosstool-NG.sh:
- fix Makefile to really, really not used built-in rules and variables
- have scripts/crosstool-NG.sh generated from scripts/crosstool-NG.sh.in
- create a bin-overide directory ( in ${CT_WORK_DIR}/bin ) that contains shell wrappers to the actual discovered tools
