Hans-Peter Nilsson a6837ca34f Committed, CRIS port: fix fallout from time_t defaulting to 64 bits, part 1
It's been a while...  I see the CRIS port broke with the
time_t-default-to-64-bit change, observable by a few test-cases in the
gcc fortran(!) tests failing, regressing when trying a recent newlib.

This is a two-part belt-and-suspenders change: adjust the CRIS port
gettimeofday syscall (the only one in newlib/CRIS passing a time_t or
struct timeval) to handle a userspace 64-bit time_t and secondly default
time_t to 32-bit long anyway.  I considered making the local
"kernel_timeval" copy in _gettimeofday conditional on (userspace) time_t
being 64 bits, but thought it not worth bothering with the few move insns.
The effect of a 64-bit time_t is however observable as longer simulation
time when running the gcc testsuite and as bigger binaries without any
actual upside from the larger time_t size, so I thought better make the
default for this port go back to being a "long" again.

Tested by running the gcc testsuite over the three combinations of two
parts of the patch and observing the expected changes.  Committed.

libgloss:
	Adjust for syscall and userspace having different time_t or timeval.
	* cris/linunistd.h (kernel_time_t, kernel_suseconds_t, kernel_timeval):
	New types.
	(gettimeofday): Change the type of the first argument to be a
	pointer to a struct kernel_timeval.
	* cris/gensyscalls (_gettimeofday): Use an intermediate struct
	kernel_timeval for the syscall and initialize the result from
	that.
