avoid referencing address of extern function from vdprintf
this change is in preparation for upcoming PIC/shared library support. the intent is to avoid going through the GOT, mainly so that dprintf is operable immediately, prior to processing of relocations. having dprintf accessible from the dynamic linker will make writing and debugging the dynamic linker much easier.
