Minor fix to COFF .section change

[Mark E.]

Hi guys,
Looks like I found one more reason to post. It turns out SEC_LOAD may not be so good as 
a default. For example, ".section .eh_frame" according to objdump:

ehframe.s:

.section .eh_frame

  3 .eh_frame     00000000  00000000  00000000  00000000  2**2
                  ALLOC, LOAD, CODE

Ouch. Not only does this cause crashes when throwing a C++ exception if the default is 
treated as code, but it's contrary to my reading of the .section docs. I didn't think 
SEC_LOAD by itself would add SEC_ALLOC and SEC_CODE, but looking at styp_to_sec_flags 
and sec_to_styp_flags reveals this to be true. I believe the right thing to do is make 
the default so that SEC_CODE can't be added and guarantee that the section is writable 
according to the docs.

	* config/obj-coff.c (obj_coff_section) [BFD_ASSEMBLER]: Make the
	  default section flags 'SEC_LOAD | SEC_DATA' to prevent the section
	  from mistakenly being marked as code when output.
