Patch to fix build breakage with GCC 4.7

[David Holmes]

Hi Deepak,

The primary change here is a build change so I've cc'ed build-dev.

The majority of the changes are to JVMTI demo files hence I've cc'd 
serviceability-dev.

I think JDK8-dev doesn't need to be included now so I've bcc'd it.

While gcc compilation on sparc is rare I'm not sure that simply deleting 
the sparc-only option unconditionally is the right thing to do.
