Indeed, but my IRIX 6.5 host is dead slow (full bootstrap and N32/N64 make
check takes about 4 days).  Perhaps someone else can try a bootstrap on
mips-sgi-irix6.[25] with my patch (included below for reference)?

Fine, thanks.

It's in now.

	* 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.
