I am not doing a native ARM build.  I am cross-compiling on Ubuntu x64 14.04 using
the configure command that I posted earlier.  The cross-compile to ARM is working
but the build also creates something called buildjdk that is a native x64 version.
For this, it uses the system 4.8.4 x64 toolchain that comes with Ubuntu 14.04.
It is this x64 link of the buildjdk version of libjvm.so that is failing.
