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.

I'm glad we agreed on the new syntax. It aligns nicely with the existing SRC syntax, and there is no ambiguity or symbols like `@` with special meaning (I was not fond of that either, but could not figure out a better way to mimic the old syntax). It is a bit longer, and a line like this is a bit hard to read:

    JDK_LIBS := java.base:libjava java.base:libjli java.base:libjvm, \

but I guess that is a price we just have to pay.
