Change 95410 by jb at jb_freebsd2 on 2006/04/17 04:33:11

	Add a bucket load of ctfconvert statements to the default rules
	so that whenever an object is built, it will have it's DWARF
	debug info converted to CTF. If DEBUG_FLAGS were set, then the CTF
	info is added rather than replacing the DWARF stuff.
	
	Note: This only applies to the default rules. There are lots and
	lots of places in the Makefiles where custom compilation takes
	place. All these need the ctfconvert statements added. That is
	work for much later. For now, what we've got is something that we
	can work with for proof of concept. It's not expected to be
	thorough yet. That's why I made the ctfconvert and ctfmerge tools
	not fail if the CTF info isn't present.
	
	We've got work to do to all the assembler code to get DWARF
	data generated. At the moment, every assembler file compiled to
	an object contains none of the required info for CTF. That's work
	for later too.
