In Jake, when crosscompiling, we need to build a subset of the jdk, including hotspot, to be able to run jmod and jlink. Currently, the build compiler is just found on the system so such a configuration requires the build system to basically be able to compile the jdk without a devkit. The idea with devkits was partly to avoid this.

The solution would be to add another configure parameter that defines a devkit for the build compiler.
