	* Configure (1.294), Makefile.org (1.142): For systems where gcc is
	used and where we don't know if GNU ld is used or not, let's ask
	collect2 which ld it uses and choose to use the target
	do-gnu_shared if GNU ld is used.

	This solves the reported problems on Solaris systems where GNU cc
	is used but GNU ld isn't, and probably on other systems with
	similar setups.
