Actually, you don't need to special handle this. Libtool does it for
you. Passing -lneon to a libtool link line is all you need to do
(libtool will search for the .la itself).

(from libtool)

for searchdir in $newlib_search_path $lib_search_path $sys_lib_search_path $shlib_search_path; do
  # Search the libtool library
  lib="$searchdir/lib${name}.la"
  if test -f "$lib"; then
    found=yes
    break
  fi
done
