[git commit nptl] add a wchar.h stub

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=44896253aab05ab2d41143337761859250f0cea4
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/nptl

The basic C standard requires a few wchar types, so provide those even when
wchar support is disabled.
