DJGPP COFF patches

["Mark E." <snowball3@bigfoot.com>]

The attached patch implements COFF .gnu.linkonce support 
(presented again so it's synced against late yesterday's CVS) plus the 
config changes needed so DJGPP can use it. 

I've tested with BFD assembler and non-BFD assembler. My test case 
worked as expected (just one copy in the final .exe) and the value 
printed was correct. 

Changelog for BFD: 

1999-07-20 Mark Elbrecht <snowball3@bigfoot.com> 

* coffcode.h (styp_to_sec_flags) [COFF_LONG_SECTION_NAMES, 
COFF_SUPPORT_GNU_LINKONCE]: Sections whose names begin 
with .gnu.linkonce are marked with the flags SEC_LINKONCE and 
SEC_LINK_DUPLICATES_DISCARD. This is an optimization for GNU 
C++.
