RFR: JDK-8198859 Use elfedit to silence linker warnings on solaris

Thu Mar 1 10:01:51 UTC 2018

Solaris builds have always produced a lot of warnings when linking, like 
this:

ld: fatal: symbol '__JvmOffsets' has differing types:
     (file 
/export/home/magnusi/hg/sandbox-cflags/build/solaris-sparcv9/hotspot/variant-server/libjvm/objs/JvmOffsets.o 
type=OBJT; file 
/export/home/magnusi/hg/sandbox-cflags/build/solaris-sparcv9/hotspot/variant-server/libjvm/objs/dtrace_jhelper.o 
type=FUNC);

This is due to an unresolved bug in dtrace. This bug has been reported 
on the dtrace team in 2014, but no solution have been coming forth. :-( 
However, I just discovered that we can actually use elfedit to fix the 
type of the fields that the linker is complaining about on 
$(DTRACE_JHELPER_OBJ).

That will make the linker quiet.
