I don't think so. GCC on sparc64-*-linux is supposed to default to
-mcpu=ultrasparc if no -mcpu= is given.

There used to be a bug in this area, but it should be fixed by my:
* config/sparc/linux64.h (OPTION_DEFAULT_SPECS): If SPARC_BI_ARCH,
override sparc.h definition.
patch.
asm_cpu_default is supposed to be used, because no -mcpu=* nor one of its
obsolete variants are used.
