This is a hotspot issue. The message is informational. Support was added 
a while ago to hook Dtrace into systemtap if it was available - 
sys/sdt.h is present. If not you get the message.

Jon is right that this is something that could be handled by configure 
but as I've explained in the bug report hotspot only tolerates 
configure, it doesn't fully integrate with it. So you really need two 
issues filed:
- one for configure to take an option to deal with this
- one for hotspot to respond to whatever make variable configure sets

The same could be said for a dozen flags in the hotspot build. But if 
everything becomes a configure option then configure will be too 
unwieldy to use.
