Still I need to select sparc_cpu and too. I could then add -mtune=leon at
compiletime to switch sparc_cpu, but the I have to give -mtune=leon every time.
I would like to be able to make it the default. With just
 [ --with-cpu=v7/v8 | --with-float=soft/hard | --disable-multilib ]  to configure
you cant.
So then my suggestion would be to use tripple
 [ --with-cpu=sparcleonv7/sparcleonv8 | --with-float=soft/hard | --disable-multilib ]
to configure. And add the 2 cpu types sparcleonv7,sparcleonv8 that would replace
Does this sound good?
