-mcpu vs. binutils 2.13.90.0.18

[Guido Guenther <agx@sigxcpu.org>]

Hi,
it seems newer binutils doen't know about -mcpu anymore. Is it correct
to simply change:
 -mcpu=r5000 -mips2 -Wa,--trap
to
 -mtune=r5000 -mips2 -Wa,--trap
for IP22? -mips2 conflicts with -march=r5000 since this implies -mips4.
