obj-coff.c: coff_frob_section patch

[Mark E.]

Hi guys,

When the last section is aligned for a COFF target using BFD, garbage is 
written out unless padding is added.

gas/Changelog:

2000-07-11  Mark Elbrecht  <snowball3@bigfoot.com>

	* config/obj-coff.c (coff_frob_section): Add padding to the last
	  section when aligning it increases its size.
