2aea48249d 8062672: JVM crashes during GC on various asserts which checks that HeapWord ptr is an oop 
Crashes were caused by not disabling UseMemSetInBOT as should be done on sparc. Added support for picking up blkinit as a platform feature if available on Linux sparc. This is needed to avoid enabling UseMemSetInBOT when running on this platform.
