[kaffe] m68k/linux with jthreads

[Kiyo Inaba]

Hi,

I was frustrated for having some non-deterministic errors happened on
this platform for long time. I finally can figure out why it happens
(in some sence). It was caused by wrong behavior of 'setitimer' for
m68k/linux. So my proposed patch attacheched disable the use of
'setitimer' for this platform. This patch solves above error with
jthreads and the regression tests 'only' fails 46 test cases.
# BTW, recently pthreads works for this platform with 44 fails.

ChangeLog entry can be:

	* config/m68k/linux/config.frag:
	Disable the use of 'setitimer' even if it is available.
