I can, once there's agreement on the complete configure.host vs. .target
and libgcj.spec changes. My current proposed patch is included below; I'll
test it later this week.

* configure.target: Renamed from configure.host.
Changed host to target references.
Introduce target_cpu and target_os switches, moving cpu- or
os-only sections here.
* Makefile.am (CONFIG_STATUS_DEPENDENCIES): Reflect this.
* acinclude.m4: Likewise.
* Makefile.in: Rebuilt.
* aclocal.m4: Likewise.
* configure.target (REFERENCESPEC): New.
* libgcj.spec.in (jc1): Use it.
* configure.in (REFERENCESPEC): Substitute it.
* configure.target (i?86-*-solaris2*): Keep default DIVIDESPEC.
* configure.target (solaris2*, mips-sgi-irix6*): Use
-fcheck-references for REFERENCESPEC.
