0515494aac For sections containing uninitialised data, only set their size to s_paddr
if this does not reset their size to zero.  MS's latest compilers will set
s_paddr to zero.

12d0ee4aca Avoid creating COPY relocs if possible.

	track of space we allocate using pcrel_relocs_copied.

	and .plt rather than comparing section names.
