RFR (XS) 8031064: build_vm_def.sh not working correctly for new build cross compile

[David Holmes]

Hi Dean,

Code reviews don't go to jdk9-dev. Build-infra is not relevant to this 
either. You only need hotspot-dev for a hotspot build issue (though 
build-dev might be useful for more complex changes).

I'm always wary of things that might be shell specific:

   vm.def: $(Res_Files) $(Obj_Files)
!         NM=$(NM) sh $(GAMMADIR)/make/linux/makefiles/build_vm_def.sh 
*.o > $@

I use this style of shell script invocation a lot from bash, where it 
works, but I was under the impression not all shells support it.
