By default `JDK_FOR_COMPILE` is set to `$(JDK_IMAGE_DIR)`, which is the same as `JDK_UNDER_TEST`. `JDK_FOR_COMPILE` can be set to an alternative JDK directory that is different from the JDK running the tests. For jtreg testing on the new `static-jdk` image (the static JDK built by `static-jdk-image`), this becomes useful. The `static-jdk` binary is a subset of the regular `jdk` and only contain the needed files for the `static` Java launcher. `JDK_FOR_COMPILE` can be set to a JDK directory containing the full JDK binary. For example:
> 
> `$ make test-tier1 JDK_IMAGE_DIR=/.../JDK-8348905/build/linux-x86_64-server-release/images/static-jdk JDK_FOR_COMPILE=/.../JDK-8348905/build/linux-x86_64-server-release/images/jdk`
