Stub out localeconv. Please look over this to check it is correct....

I started trying to read the glibc code -- but that code is far too
messy to be read.  So I just wrote a silly C app against glibc, set
the locale to POSIX, then called localeconv().  I wrote this version
of localeconv.c so it returns the same stuff.
