patch

Jacek was kind enough to cross compile (using llvm-mingw) an armv7 winetest
binary for me.

I tried running that on my rooted Surface RT tablet (windows 32-bit armv7), and
it immediately fails with an error dialog:
The procedure entry point NtCurrentTeb could not be located in the dynamic link
library C:\Users\User\Desktop\winetest.exe

<jacekc> it looks like NtCurrentTeb is not exported by windows ntdll. looking
at windows headers, there is an inline version
<jacekc> it should use _MoveFromCoprocessor. I don't know enough about arm to
know how hard it is to support

Using an inline definition instead allows the tests to run. I'm attaching
Jacek's patch that does that for reference.
