cmake: support to create per-toolchain cmake file in SDKkirkstone-next
The patch creates ${MULTIMACH_TARGET_SYS}-toolchain.cmake file at ${SDK_INSTALL_DIR}/sysroots/${SDK_SYS}/usr/share/cmake/, which is per-toolchain CMake toolchain file containing arch-specific values and independent of OE environment variables. The file gets created after installing SDK toolchain installer ined by running "bitbake -c populate_sdk <image>". The changes are similar to meson-setup.py which is used to create arch-specific ${SDK_INSTALL_DIR}/sysroots/${SDK_SYS}/usr/share/meson/*-meson.cross [YOCTO #14644] Tested-by: Jan Dorniak <jaskij@gmail.com> Signed-off-by: Jagadeesh Krishnanjanappa <workjagadeesh@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
