This is the pinnacle of the recent stream of refactorings in the build system. This patch introduces a more abstract concept of "JDK_LIBS", where only the library name (e.g. "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.
