Hi, please review the following change as a follow up to an earlier discussion here: http://mail.openjdk.java.net/pipermail/build-dev/2019-December/026408.html
On Windows it's not possible to support configure option "--with-native-debug-symbols=internal" in a way that one would expect. E.g. native debug information should be part of the binaries while on Windows it's only possible to have the debug information in external .pdb files. So it seems natural to reject "--with-native-debug-symbols=internal" on Windows. In my proposed patch I change this, together with some minor correction for AIX and a little cleanup. I also repair a build error that would currently happen in gtest image if one is to build target 'images' on Windows while having set "--with-native-debug-symbols=internal". Note that this path could not be taken any more, though. I only added this for completeness since I ran over it during my experiments. An alternative to rejecting "--with-native-debug-symbols=internal" would be to implicitly convert it to "--with-native-debug-symbols=external" but I think it is better if the user gets the feedback that the option he intended to use won't work.
