Patch checked in.

In general, the local.h headers are not meant to cross directories.  
They are allowed to define things without worrying if another directory 
has chosen to define the same symbols in their local.h.

I have no problem with the current situation, but we could conceivably 
create another header in libc/locale (e.g. internal_locale.h) and have 
the local.h files in question include that header.
