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

# This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
yann@1156
     5
# to set additional flags in the current Makfile ( see:
yann@1156
     6
# http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
yann@1156
     7
# should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
yann@1156
     8
# so we have to work it around by calling ourselves back if needed
yann@1156
     9
yann@1156
    10
# So why do we need not to use the built rules and variables? Because we
yann@1156
    11
# need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
yann@1156
    12
# and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
yann@1156
    13
# nor a command associated, and that built-in implicit rule takes precedence
yann@1156
    14
# over our non-built-in implicit rule '%: %.in', below.
yann@1156
    15
