Apply again [916352f2] that got lost in the merges.

Do not quote second argument to filter{,_out} in check_ld. We want to keep/remove all the space-separated words matching the -l* pattern, not keep everything if the whole argument begins with -l and remove it otherwise.

This also fixes errors like:
./configure: eval: line 418: syntax error near unexpected token `-l*'
./configure: eval: line 418: `case  in -l*) ;; *) echo  ;; esac'
when run with ./configure --enable-openal
