[PATCH] Clean up arch-overrides in linux/string.h
Some string functions were safely overrideable in lib/string.c, but their corresponding declarations in linux/string.h were not. Correct this, and make strcspn overrideable. Odds of someone wanting to do optimized assembly of these are small, but for the sake of cleanliness, might as well bring them into line with the rest of the file.
