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

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch

     2 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,

     3 you have to actually list out the multilibs you want or you will end up with

     4 just one when using targets like 'sh4-linux-gnu'.

     5 

     6 The resulting toolchain can't even build a kernel as the kernel needs to build

     7 with the nofpu flag to be sure that no fpu ops are generated.

     8 

     9 Here we restore the gcc-3.x behavior; the additional overhead of building all

    10 of these multilibs by default is negligible.
