[Bug c++/18621] New: VTABLE emits unused bytes on avr target

["intelliguy_sa at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling C++ class with virtual methods results in virtual table that looks
like this:
  98               	_ZTV11auzaBilling:
  99 0000 0000      		.word	0
 100 0002 0000      		.word	0
 101 0004 0000      		.word	pm(_ZN11auzaBillingD1Ev)
 102 0006 0000      		.word	pm(_ZN11auzaBillingD0Ev)
 103 0008 0000      		.word	pm(_ZN11auzaBilling14prepareBillingEv)

After reviewing assembly listing, I found out that first 4 bytes are not used
anywhere. Is there a way to prevent compiler (like "-no-rtti") from generating them?
