build: remove the variable NM in gen_ll_addressable_symbols.sh
With LTO activated, the buildman tools failed with an error on my configuration (Ubuntu 20.04, stm32mp15_trusted_defconfig) with the error: ../arm-linux-gnueabi/bin/nm: scripts/gen_ll_addressable_symbols.sh: file format not recognized It seems the shell variable initialization NM=$(NM) is not correctly interpreted when shell is started in the Makefile, but I have not this issue when I compile the same target without buildman. I don't found the root reason of the problem but I solve it by providing $(NM) as script parameter instead using a shell variable. The command executed is identical: cmd_keep-syms-lto.c := NM=arm-none-linux-gnueabihf-gcc-nm \ u-boot/scripts/gen_ll_addressable_symbols.sh arch/arm/cpu/built-in.o \ .... net/built-in.o >keep-syms-lto.c cmd_keep-syms-lto.c := u-boot/scripts/gen_ll_addressable_symbols.sh \ arm-none-linux-gnueabihf-gcc-nm arch/arm/cpu/built-in.o \ ... net/built-in.o > keep-syms-lto.c Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>
