DJGPP linker script patch r3

["Mark E." <snowball3 at bigfoot dot com>]

Hello again:

This revision adds support for symbols that have their own unique 
section, to allow 
for gc by the linker when --gc-sections support for COFF is added.

ld/Changelog:

1999-10-19 Mark Elbrecht <snowball3@bigfoot.com>

	* scripttempl/i386go32.sc (___EH_FRAME_BEGIN__): Delete.
	  (___EH_FRAME_END__): Delete.
	  (_etext, _end): Move the semicolon inside the brace.

	* scripttempl/i386go32.sc: Support prioritized constructors
	  and destructors.
	  Support symbols that have their own unique section.
