MIPS: Allow the auxv's elf_platform entry to be set.
The userspace runtime linker uses the elf_platform to find the libraries optimized for the current CPU archecture variant. First we need to allow it to be set to something other than NULL. Follow-on patches will set some values for specific CPUs. GLIBC already does the right thing. The kernel just needs to supply good data.
