# Pass1: Determine CROSS_COMPILE only.
|
|
# We need CROSS_COMPILE in order to validate various KBUILD_CFLAGS
|
|
# GCC CROSS_COMILE is needed in order to validate compiler options
|
|
# via constructs such as:
|
|
# KBUILD_CFLAGS += $(call cc-option,-option,)
|
|
#
|
|
# Pass2: Determine LIB_INCLUDE_DIR and TOOLCHAIN_CFLAGS.
|
|
# Knowing KBUILD_CFLAGS, we can query GCC compiler for the location
|
|
# of the libraries corresponding to the KBUILD_CFLAGS.
