Hi,

    gdbserver does not compile for the Android operating system
because of missing headers sys/user.h and sys/dir.h and a declaration
of errno inside a function.  The following patch fixes these problem.
Does it look okay? If so, could someone approve and commit it for me?
Thanks.

        * 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): Declare errno if STDC_HEADERS is not defined.
