arch/sh/Makefile defines and exports ld-bfd to be used by
arch/sh/boot/Makefile and arch/sh/boot/compressed/Makefile.  Similarly
arch/sh/boot/Makefile defines and exports suffix-y to be used by
arch/sh/boot/compressed/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.

Rename these variables to ld_bfd and suffix_y.
