from configure rather than substitute it from Makefile. Eventually we might want to get rid of configure.in completely, doing on-the-fly checks at the time of `ct-ng build`, but that is left for another day. Signed-off-by: Alexey Neyman <stilor@att.net>

# Makefile.in for building crosstool-NG

# This file serves as source for the ./configure operation
|
|
|
|
# This series of test is here because GNU make 3.81 will *not* use MAKEFLAGS
|
|
# to set additional flags in the current Makfile ( see:
|
|
# http://savannah.gnu.org/bugs/?20501 ), although the make manual says it
|
|
# should ( see: http://www.gnu.org/software/make/manual/make.html#Options_002fRecursion )
|
|
# so we have to work it around by calling ourselves back if needed
|
|
|
|
# So why do we need not to use the built rules and variables? Because we
|
|
# need to generate scripts/crosstool-NG.sh from scripts/crosstool-NG.sh.in
|
|
# and there is a built-in implicit rule '%.sh:' that has neither a pre-requisite
|
|
# nor a command associated, and that built-in implicit rule takes precedence
|
|
# over our non-built-in implicit rule '%: %.in', below.
|
|
|
|
# CT_MAKEFLAGS will be used later, below...
|
|
|
|
# Do not print directories as we descend into them

|

|
|
|
|
# Use neither builtin rules, nor builtin variables
|
|
# Note: dual test, because if -R and -r are given on the command line
|
|
# (who knows?), MAKEFLAGS contains 'Rr' instead of '-Rr', while adding
|
|
# '-Rr' to MAKEFLAGS adds it literaly ( and does not add 'Rr' )
|
|
# Further: quad test because the flags 'rR' and '-rR' can be reordered.
