Here is a snippet of a patch that explains this situation.  Hopefully
the comment is sufficient.

  -OTHER_RELOCATING_SECTIONS=${OTHER_RELOCATING_SECTIONS-'
  +
  +# Do not use the ${varname-${varname}} construct here; there will be
  +# problems with some shells (e.g. on Solaris) since there is a bug
  +# that trigs when the incoming macro value contains a "}".
  +test -z "$OTHER_RELOCATING_SECTIONS" && OTHER_RELOCATING_SECTIONS='
    .foo 0 : { *(.foo) }
    .stack 0x30000 : { _stack = .; *(.stack) }
  -'}
  +'
