Folks:
	I haven't had a chance to figure out if this is quite the right
	thing or not -- at least from the POV of the specified behaviour,
	but the following small patch makes my ld.elf_so behave correctly
	in the face of the application overriding symbols from shared libs,
	as is done in at least the following places:
		* perl (used during build, the broken ld.elf_so caused the
		  perl build to fall over).
		* bash/tcsh (both define their own free/malloc -- with the
		  -current ld.elf_so, parts of the app use the app-defined
		  malloc/free while other parts use the libc free).

	I'll try and figure out what the right things from a spec POV are
	soon, but at least this gets me up and running (which is the key
	things for me now 8-) again.

	This addresses a bunch of PR's in GNATS as well, so if someone 
	wants to pick this up ASAP, verify that this is indeed correct,
	check it in and close those PR's, I won't complain... I will try
	and get to all that, but probably not in the next week or ten
	days...

	BTW, this is on a system post-binutils-2.13.2.1 update and with
	the stock 2.59.3 gcc.
