linux-yocto: depend on libgcc for aarch64
Make aarch aarch64 kernel depend on libgcc. In arch/arm64/Makefile, it adds LIBGCC to libs-y: LIBGCC := $(shell $(CC) $(KBUILD_CFLAGS) -print-libgcc-file-name) libs-y += $(LIBGCC) In file Makefile in top directory, libs-y is assigned to to var KBUILD_VMLINUX_MAIN. It uses script link-vmlinux.sh to link vmlinux.o, and when execute function vmlinux_link() in link-vmlinux.sh, KBUILD_VMLINUX_MAIN is passed to ${LD}. If build without libgcc, the value of LIBGCC is just libgcc.a without parent directory. linux-yocto fails to build: | LD vmlinux.o | aarch64-poky-linux-ld.bfd: cannot find libgcc.a: No such file or directory Add libgcc to aarch64 kernel dependency.
