After further investigation the error I encountered was caused by GNU Make 4.0. Erik Joelsson from Oracle kindly provided a patch [1] and I've been able to build the compact JREs.
I did a quick test with headless applications to see the difference in startup time between the full JRE and the compact1 profile. I measured the time to run 'mvn -version' and 'ant -version' 100 times. The compact JRE was faster by 6-7% only. With clirr the compact JRE was ~13% faster. With an average startup time of ~100ms the difference was hardly noticeable. Now I wonder if packaging the compact JREs is really worth the trouble.
