I repeat again that -march= provides the wrong information for the
PowerPC port. One wants a simple way to specify both architecture and
scheduler tuning; -mcpu= provides that information. -march= primarily is
useful for processors in which each chip extended the architecture like
x86 and Alpha, not for processors where an ISA was designed and maintained
like PowerPC.
