arch/sh/Makefile defines and exports ld-bfd to be used by arch/sh/boot/compressed/Makefile and arch/sh/boot/romimage/Makefile. However some shells, including dash, will not pass through environment variables whose name includes a hyphen. Usually GNU make does not use a shell to recurse, but if e.g. $(srctree) contains '~' it will use a shell here. Other instances of this problem were previously fixed by commits2bfbe7881e"kbuild: Do not use hyphen in exported variable name" and82977af93a"sh: rename suffix-y to suffix_y". Rename the variable to ld_bfd.
