native debug symbols support on Windows

[Erik Joelsson]

Correct, with the Microsoft toolchain there is no support for internal. 
I don't know what happens to the build if you try to configure it that 
way. Feel free to come up with a reasonable behavior.

However, to my knowledge, Windows would always make use of external symbol files, named *.pdb. And there is no way to have the debug symbols included in the binaries. Is that correct or am I wrong in this assumption?

Otherwise, if we were to support --with-native-debug-symbols=internal, the build is broken for target "test-image" when it comes to building/copying the gtest image.
