[gdbserver] return ENOSYS if readlink not supported.
This reproduces on the GDBserver side what GDB does when readlink is
not supported.
gdb/gdbserver/ChangeLog:
* configure.ac: Add readlink to AC_CHECK_FUNCS list.
* configure, config.in: Regenerate.
* hostio.c: Provide an alternate implementation if HAVE_READLINK
is not defined.
