`make bootcycle-images` broke after JDK-8349665, with the symptom:
jdk.internal.md.interim/module-info.java:51: error: module not found:
jdk.compiler.interim
requires jdk.compiler.interim;
This is since the bootcycle build use a special spec.gmk files which point to a
special `make-support` directory, and this did not contain the necessary files
needed to start running make targets. (Ever since JDK-8292944 they need to be
explicitly generated.)
