Subject: [PATCH] kbuild: Fix cross compile link with ccache

Fix calling objcopy in case of cross compile environments:

	ARCH="arm" CROSS_COMPILE="ccache arm-linux-gnueabi-" make
	scripts/link-vmlinux.sh: line 211: ccache arm-linux-gnueabi-objcopy: command not found

Fixes: 6a26793a7891 ("moduleparam: Save information about built-in modules in separate file")
