3.1 PATCH: libjava configure.host updates for Solaris 2/IRIX 6/Tru64 UNIX

[Rainer Orth <ro at TechFak dot Uni-Bielefeld dot DE>]

I had already submitted a version of this patch

	http://gcc.gnu.org/ml/java/2002-03/msg00605.html

which Tom ok'd for branch and trunk:

	http://gcc.gnu.org/ml/java/2002-04/msg00026.html

Since the file has changed considerably since my original patch, here's an
updated one, verified by bootstrapping on sparc-sun-solaris2.5.1,
sparc-sun-solaris2.8, i386-pc-solaris2.8 and alpha-dec-osf5.1.

This patch tries to clearly separate between per-cpu, per-os and
triplet-specific properties.  Unfortunately, it is hard to read in both
unidiff and context-diff formats.

Ok for branch and trunk?

	Rainer

	* configure.host: Introduce host_cpu and host_os switches, moving
	cpu- or os-only sections here.
	Sort host switch.
	(solaris2*, alpha*-dec-osf*, mips-sgi-irix6*): Use
	-fcheck-references for CHECKREFSPEC. 
	(i?86-*-solaris2*): Keep default DIVIDESPEC.
