This does not catch all cases. There is also
 yes)
   if test x${default_ld} != x; then
     install_gold_as_default=yes
   fi
   ;;

which needs an "else" case, as far as I can see.
"default_ld" is empty for the normal cases, unless you set --enable-ld=no.

Or you fix the if statement some few lines below:
