        * libc/sys/linux/bits/dirent.h: New header file.
        * libc/sys/linux/sys/dirent.h: Include <bits/dirent.h> instead of
        <linux/dirent.h>.
        * libc/posix/Makefile.am: Remove reallocf.
        * libc/posix/Makefile.in: Regenerated.
        * libc/posix/reallocf.c: Moved to...
