<!--
    This is an example of how to add custom compiler/linker 
    arguments for a crosscompiler.

    You can use such files with setting the property 'gluegen-cpptasks.file', ie:

        -Dgluegen-cpptasks.file=`pwd`/lib/gluegen-cpptasks-linux-32bit.xml

    In case you want to compile for 32bit on a 64bit machine,
    you might also need to set the 'os.arch' to 'x86'.
    Example: gluegen/make/make.gluegen.all.linux-x86.sh
      -->
