Seems to work like this:

 $ mkdir graal-test-libs
 $ cd graal-test-libs
 $ wget (JARs mentioned in README.md)
 $ cd ..

 $ sh ./configure ... --with-graalunit-lib=graal-test-libs/
 $ make run-test TEST=compiler/graalunit TEST_VM_OPTS="-XX:+UnlockExperimentalVMOptions
-XX:+EnableJVMCI -XX:+UseJVMCICompiler -Djvmci.Compiler=graal"

With one little wrinkle:
