Committed: update simulated Linux for sim/cris

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

Update from 2.4.5 to 2.6.27, so I don't get a "FATAL: kernel too
old" for all programs linked with a newer glibc, which require a
kernel this new for TLS support (upcoming patch).  And, of
course the date would be humorous but unpossible or at least
imcorrect, so better fix that.  And, the machine type wasn't set
correctly.  (And, a TODO: pass the kernel version some better
way than parsing uname.)

Committed.  (And fixing a nit in the previous ChangeLog format.)

sim/testsuite:
	* sim/cris/c/uname1.c: New test.

sim:
	* cris/traps.c (TARGET_UTSNAME): Update to 2009-01-01.
	(TARGET_EPOCH): Update to match TARGET_UTSNAME.  Correct comment.
	(cris_break_13_handler) <case TARGET_SYS_uname>: Update to
	2.6.27.  Set machine field to the BFD printable name of the
	machine.
