[MIPS] Update asm string header
This patches contains several bugfixes and cleanups in the latest upstream:
- Don't include linux/config.h
- Remove buggy inline version of memscan.
- Merge with Linux 2.6.11-rc3.
- Fix undefined reference to strcpy in binfmt_misc caused by gcc 3.4.
- Goodbye mips64. 31704 lines of code bite the dust.
- Replace extern inline with static inline.
- Fix return value of strncpy.
- Remove a bunch more "$1" clobbers.
