Subject: rlimit: var init problem due to large file offset.

Now that we fixed the regression in detecting whether to use
-D_FILE_OFFSET_BITS=64, this has unmasked an issue in newer
code. In sysif.c, the RLIM_INFINITY, and related constants,
are being passed to num_fast: but they are 64 bit unsigned
constants under the large file offset, which don't fit into a
cnum or unum on a 32 bit system.

* configure: When we detect large file offset, we deposit
the tell-tale configuration constant CONFIG_LARGE_FILE_OFFSET
into config.h.

* sysif.c (sysif_init): Under CONFIG_LARGE_FILE_OFFSET,
treat the RLIM_ constants using bignum_dbl_uipt.
