[PATCH][gdbserver] Check for sys/dir.h and sys.user.h in configuration.

[Doug Kwan (關振德)]

I used the autoconf-2.59.tar.bz2 from ftp.gnu.org. I got fewer spurios
diffs than before but there still seems to be some left.  Here is an
updated patch.

        * configure.ac: Check for sys/dir.h and sys.user.h.
        * config.in configure: Regenerate.
        * linux-low.c: Include <sys/dir.h> if HAVE_SYS_DIR_H is defined.
        Include <sys/user.h> if HAVE_SYS_USER_H is defined.
        (linux_write_memory): Remove declaration of errno.
