Removing the line shouldn't cause any problems.

It's normally in "/usr/X11/lib". If it is installed, but the
"configure" script can't find it, you can use the "--x-libraries"
argument to force a specific directory.

The ones for which <sys/select.h> was being used are the fd_set type
and the FD_ZERO and FD_SET macros. In GNU libc 2, these are defined in
<sys/select.h> but that file is included from <sys/types.h>. The
latter is apparently the correct file to include for these
definitions.
