Subject: [PATCH] arm: Use __WCHAR_TYPE__ for wchar_t if defined
When building with -fshort-wchar the definition of wchar_t is
incorrect. Get the correct definition from the compiler if available.
This is useful when reusing the freestanding parts of musl on a
bare-metal target that uses -fshort-wchar.
