building a biarch compiler on sparc-linux-gnu --with-cpu=v9

[Matthias Klose]

I'm currently building trunk on sparc-linux-gnu (32bit) configured with

  --enable-targets=all --with-cpu=v8

trying to change that to

  --enable-targets=all --with-cpu=v9

two 64bit libgcc's are built. it looks like v9 and 64bit are tightly
coupled in the configury. how can this be setup to build a biarch
compiler which defaults to v9/32bit?
