Handle AC_SEARCH_LIBS special result value. AC_SEARCH_LIBS will give a result of "none required" if the relevant function is available without any special libraries. This is the case for lrintf on MinGW. Make sure this special value isn't put verbatim into the pkg-config files, as it would cause the linker to search for files named "none" and "required", and fail. Signed-off-by: Timothy B. Terriberry <tterribe@xiph.org>
