* libc/include/sys/config.h[__i386__][__linux__]: Define
_LARGE64FILE_SOURCE to 1.
* libc/sys/linux/Makefile.am: Add getrlimit64.c and setrlimit64.c.
* libc/sys/linux/Makefile.in: Regenerated.
* libc/sys/linux/resource.c: Add __getrlimit and __setrlimit aliases.
* libc/sys/linux/sys/linux_time.h: Protect struct timeval definition.
* libc/sys/linux/sys/resource.h: Include <bits/resource.h> instead
of <linux/resource.h>.
* libc/sys/linux/getrlimit64.c: New file.
* libc/sys/linux/setrlimit64.c: Ditto.
