string: remove more pointless __HAVE_ARCH_STR*

Browse Source 
None of these six macros are defined by any architecture. Moreover,
the ifndef guard only exists in either string.h or string.c, making them
completely pointless.

I'm not sure whether we have an explicit coding style discouraging the
"extern" qualifier on function declarations, and string.h has a random
mix of everything, but I can't leave it on strncasecmp() now that it
will be immediately after strcasecmp() which doesn't have it.
