[ Upstream commit c32969d036 ]
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 commits
2bfbe7881e "kbuild: Do not use hyphen in exported variable name"
and 82977af93a "sh: rename suffix-y to suffix_y".
Rename the variable to ld_bfd.
