Subject: sh: Do not use hyphen in exported variable names
|
|
|
|
arch/sh/Makefile defines and exports ld-bfd to be used by
|
|
arch/sh/boot/Makefile and 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 the variable to ld_bfd.
|
|
|
|
(Another instance of this problem was fixed upstream by commit
|
|
82977af93a0d "sh: rename suffix-y to suffix_y".)
