arch/sparc: better default CPU when targetting Linux
By default, sparc64-*-linux is configured with -mcpu=v9. However,
according to https://sourceware.org/ml/libc-alpha/2005-12/msg00027.html:
"There is no Linux sparc64 port that runs on non-UltraSPARC-I+ ISA
CPUs."
v9 is such a "non-UltraSPARC-I+ ISA CPU", so it makes no sense to
default to v9 when targetting Linux.
Change the default to ultrasparc, even though it can suboptimally
schedule instructions for newer SPARC CPUs. See the pending patch:
