RFR(XS): 8073754: Zero/PPC: StackOverflowError during build in javadoc processing.

[Volker Simonis]

Why can't you simply use:

  --with-boot-jdk-jvmargs specify JVM arguments to be passed to all java
                          invocations of boot JDK, overriding the default
                          values, e.g --with-boot-jdk-jvmargs="-Xmx8G
                          -enableassertions"

with the corresponding stack settings?
