Remove ${OBJDUMP} make variable as it is not used by the base system

[emaste]

Summary

It was added to sys.mk relatively recently in rS274503 for EFI builds but is no longer used in the base system

I don't object, but we use it in CheriBSD so I'll have to revert this change there.

Ah, we should be able to get the equivalent of the -x, -r, and -s options from readelf, but not -S or -D which are probably the most interesting :(

Yeah, we have a WANT_DUMP make file option to that runs ${OBJDUMP} -xrsSD on programs (and shortly shared libraries) to help understand instruction traces.

Ok, my proposal: I commit this for now, you can carry the revert in CheriBSD, and we'll subsequently see about improving non-binutils tools (e.g. LLVM objdump) or finding a clean way to use an external toolchain objdump.

That's fine.
