bfd/peicode.h: Handle binaries produced by the latest M$oft compilers

[Nick Clifton <nickc at cambridge dot redhat dot com>]

Hi Guys,

  I am applying the patch below so that LD for ming32w can cope with
  the binaries being produced by the latest versions of Microsoft's
  compilers.  These compielrs store the size of the .bss section in
  the s_scnlen field of the section's symbol and not in the s_size of
  the section header.

  There is code in peicode.h to handle this situation, but it was
  being overridden by the code covered with COFF_NO_HACK_SCNHDR_SIZE
  which was resetting the section's size back to zero.  The patch
  fixes this back checking for a zero value before assigning it to the
  section's size.

Cheers
        Nick

	* peicode.h (coff_swap_scnhdr_in): 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.
