gemini: image: fix race condition when building copy-kernel.bin
Make treat copy-kernel.o as intermediate and delete it when it's no longer needed. This can fail when the same submake was triggered multiple times for different devices. arm-openwrt-linux-muslgnueabi-as -k -o copy-kernel.o copy-kernel.S export MAKEFLAGS= ;make -w -C copy-kernel CROSS_COMPILE=arm-openwrt-linux-muslgnueabi- arm-openwrt-linux-muslgnueabi-objcopy -O binary -S copy-kernel.o copy-kernel.bin make[5]: Entering directory '/builder/shared-workdir/build/target/linux/gemini/image/copy-kernel' arm-openwrt-linux-muslgnueabi-objcopy -O binary -S copy-kernel.o copy-kernel.bin rm copy-kernel.o make[5]: Leaving directory '/builder/shared-workdir/build/target/linux/gemini/image/copy-kernel' # "App" partition is the rootfs arm-openwrt-linux-muslgnueabi-objcopy: 'copy-kernel.o': No such file Makefile:27: recipe for target 'copy-kernel.bin' failed make[5]: Leaving directory '/builder/shared-workdir/build/target/linux/gemini/image/copy-kernel' make[5]: *** [copy-kernel.bin] Error 1 Makefile:244: recipe for target '/builder/shared-workdir/build/build_dir/target-arm_fa526_musl_eabi/linux-gemini/tmp/openwrt-gemini-storlink_sl93512r-ext4-factory.bin' failed make[4]: *** [/builder/shared-workdir/build/build_dir/target-arm_fa526_musl_eabi/linux-gemini/tmp/openwrt-gemini-storlink_sl93512r-ext4-factory.bin] Error 2 With this change, output files are directed to $(KDIR) Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
