Use !__HAVE_LOCALE_INFO__ define to use _ctype_ directly [v2]

Browse Source 
When __HAVE_LOCALE_INFO__ is not selected, directly access the
existing _ctype_ variable from __locale_ctype_ptr() and
__locale_ctype_ptr_l(), eliminating the need for any locale or reent
structure

v2:
	locale: fix conflict with __locale_ctype_ptr macro

	If we are building without __HAVE_LOCALE_INFO__, there is a
	macro providing __locale_ctype_ptr which in turn fouls up this
	declaration.
