This patch makes GCC know about -march=34kn. MIPS asked us to add
support for this processor to our local source base a couple of years
ago; it's basically a 34Kc without the DSP ASE. OK for mainline?
I have posted the corresponding assembler patch here:

* config/mips/mips-cpus.def (34kn): New.
* config/mips/mips.h (MIPS_ARCH_FLOAT_SPEC): Add 34kn.
(BASE_DRIVER_SELF_SPECS): Do not imply -mdsp for the 34kn.
