Make target for compiling java classes only?

[Kelly O'Hair]

At one point I was experimenting with an option that would import all the
native libraries (.dll or .so files) from the JDK_IMPORT_PATH area rather
than run the native compiler. The idea was to allow for building the jdk
without having a native compiler. For various reasons I gave up on this.

I originally hoped it would be a build time performance trick a developer
who didn't change native code could use, but the build time benefits on
Linux and Solaris were not that great, and windows has it's own build
complications that didn't allow it to work very well (the separation of the
.lib and .dll files to name one, the Unix .so files serve as both).

Look at the uses of IMPORT_NATIVE_BINARIES in the jdk7/jdk/make files.
The idea was to:
    make IMPORT_NATIVE_BINARIES=true ALT_JDK_IMPORT_PATH=/.../builtjdk7
I doubt that it works anymore, but it might be helpful.
