Bug: hotspot build failed with gcc version Red Hat 4.4.6-4
     https://bugs.openjdk.java.net/browse/JDK-8047382

Summary of Fix:
Removed the Solaris specific conditionalization for casting to void * 
within calls to HS_DTRACE_PROBE* from DTRACE_CLASSINIT_PROBE* and 
DTRACE_CLASSLOAD_PROBE macro definitions.  gcc 4.4.6-4 needs this cast 
as well.  This only affects JDK 8u.  Thank you to Mario Torre for 
providing the webrev fix for this issue.

Tests:
     jprt build submission to test compilation with all compilers
     vm.quick.testlist, hotspot/test/*
     Built and testing as well with a gcc 4.4.6-4 compiler (in progress)
