Find the right runtime class path for a J9 boot jdk

[Dave Pointon]

Hiya Volker ,

Steve Poole suggested that I might 'touch base' with you, on group,
regarding your proposed change WRT the above, to whit, the change looks
good but would, I suggest, be only a local, interim fix to the problem.

Currently, I am considering a far more scaleable/generic solution based
on significantly improving the accessibility of the interface to JDK
variants - as currently presented by the extant, but as yet
undocumented, --with-jdk-variant option to configure, as a result of
which, the following condition (in jdk-boot.m4) ...

if $BOOT_JDK/bin/java -version 2>&1 | grep 'IBM J9'; then
.
.
.
fi

would become simpler, viz ...

Any version specific details, as you suggest, would then be enclosed
within the more obvious variant specific conditional block.

You'll note that I have yet to address the required presence of all the
of the extra jars listed in BOOT_RTJAR and also that I extend the
definition to add the extra jars to the end of the definition - as,
indeed, I note that you do also :-)
