In my configuration, the change https://bugs.openjdk.org/browse/JDK-8348586 , when running this command:

    make test TEST="micro:java.lang.reflect" MICRO="FORK=1;WARMUP_ITER=2"


produces:

    Building target 'test' in configuration 'build/jdk-vp'

    ERROR: Build failed for target 'test' in configuration '/build/jdk-vp' (exit code 1)

    No indication of failed target found.
    HELP: Try searching the build log for '] Error'.
    HELP: Run 'make doctor' to diagnose build problems.

This can be "fixed" by changing "INIT_CONTROL_VARIABLES" to "ALL_CONTROL_VARIABLES" on line 75:

 72 # A list like FOO="val1" BAR="val2" containing all user-supplied make
 73 # variables that we should propagate.
 74 # The '§' <=> '\ 'dance is needed to keep values with space in them connected.
 75 USER_MAKE_VARS := $(subst §,\ , $(filter-out $(addsuffix =%, $(INIT_CONTROL_VARIABLES)), \
 76 $(subst \ ,§,$(MAKEOVERRIDES))))

Please have a look at this in the context of the original change.
