This patch introduces a more abstract concept of "JDK_LIBS", where only the library name (e.g. "java" or "java.desktop:jawt") is specified, and the build system turns this into suitable linker flags: `-ljawt -L<correct path>` or `jawt.lib -libpath:<correct path>`, depending on linker. It will also automatically create proper dependencies.

In general, I have not been considering anything but the microsoft toolchain on Windows when designing this (sorry about that!), but on the other hand, I *have* had in mind that it should be easy to change if we ever get to support some other toolchain on Windows.

One of the upcoming changes I am planning is to improve handling of import libraries. I can try to make it more "microsoft"-ish rather than "windows"-ish, but then again, there are a lot of Windows checks already, and if I can hook into them I probably will.
