[PATCH 1/3] LD: vfinfo: Remove static NULL initializers

[Maciej W. Rozycki]

Remove static NULL initializers, moving the respective variables from 
data to BSS and saving some storage space.

	ld/
	* ldmisc.c (vfinfo) <'H'>: Remove static NULL initializers.
---
 This seems so obvious I find it hard to believe there is no hidden 
purpose here.  Especially as `last_bfd' placed next doesn't have an 
initializer.  But maybe there isn't a purpose really.  OK to apply?
