Build files allow for conditional switching between MQ and JBM:

-Dbuild.soa=true passed to build/build.xml builds with JBM
-Djbosstest.test.soa=true passed to testsuite/build.xml tests with JBM

Not supplying -Dbuild.soa=true will build with MQ
Not supplying -Djbosstest.test.soa will run MQ tests

The version with MQ will identify itself as EAP 4.2
The version with JBM, however, will identify itself as EAP 4.3
