i386-rtems setjmp.h patch

[Joel Sherrill]

I don't claim to fully understand why the i386 has such a complicated
path to figuring out _JBLEN but it didn't work for rtems.  Honestly I
am not sure if using setjmp-dj.h gets everything defined for targets
that
use that either.  It looks like _JBLEN of 9 is what that structure is
accomplishing.  Anyway i386-rtems targets need this one.  Please
commit it.

	* libc/include/machine/setjmp.h: Make sure _JBLEN is defined
	for i386-rtems targets.
