It seems that the first paragraph wasn't updated when the second one was 
changed. The variant with the top level makefile is the correct one.

Pass "-XP " (without the quotes, but with the space after the parameter) 
to the compiler, then it will not prepend "jvm-java-" to the java 
binary. You might also want to check your fpc.cfg as there it might add 
the cpu-os-prefix unconditionally if it detects a crosscompilation 
(check for #IFDEF CROSSCOMPILING or similar together with "-XP...").
