KBuild: Allow scripts/* to be cross compiled
Cross compiling the binaries in scripts/* is not possible
because various makefiles assume that $(obj)/whatever is
executable on the build host.
This patch introduces a new variable called KBUILD_SCRIPTROOT
that points to script/binaries to use while cross compiling.
Usage:
Build scripts for the build host:
make O=path/to/buildhost/buildscripts \
silentoldconfig prepare scripts
Then cross build script for target:
make O=path/to/target/buildscripts \
HOSTCC=$CROSS_COMPILE \
KBUILD_SCRIPTROOT=path/to/buildhost/buildscripts
silentoldconfig prepare scripts
This patch does not use KBUILD_SCRIPTROOT for all script invocations
it only redefines the following if KBUILD_SCRIPTROOT is defined.
scripts/Makefile.build
scripts/basic/fixdep --> $(KBUILD_SCRIPTROOT)/scripts/basic/fixdep
scripts/kconfig/Makefile
$(obj)/conf --> $(KBUILD_SCRIPTROOT)/scripts/kconfig/conf
scripts/mod/Makefile
$(obj)mk_elfconfig --> $(KBUILD_SCRIPTROOT)/scripts/mod/mk_elfconfig
