COFF compressed debug support

COFF compressed debug support

[Alan Modra]

Since commit 4bea06d73c04 COFF support for compressed debug sections
has been broken due to the "flags" variable not getting SEC_HAS_CONTENTS.

	* coffgen.c (make_a_section_from_file): Correct section flags
	handling.  Delete extraneous condition.  Update error messages
	to be the same as in elf.c.
