Log:
Change the wchar_t logic once more to make it a bit simplier.

A host can only have one special wchar_t definition, so we don't need to define all.
Also _WCHAR_T_DEFINED is the only definition used for overriding the wchar_t setting by
applications.
So use the previous logic to check and define the wchar_t definitions for the host and at
the end check for _WCHAR_T_DEFINED. In all cases, define _WCHAR_T_DEFINED.

Additionally, __need_wchar_t has to be undefined after including "ctype.h" as
"ctype.h" defines it.
