	I'm trying a gcc3 on 1.6U with a very slight variation on the
	--host=i386--netbsdelf2.0 patch in PR pkg/21848 (attached),
	and am not having a lot of luck. For example graphics/png
	fails to build pngtest:

	(extract from scripts/makefile.std: '-v' added to give more output)

pngtest: pngtest.o libpng.la
        ${LIBTOOL} --mode=link $(REALCC) -o pngtest -v $(CFLAGS) pngtest.o ${LDFLAGS} libpng.la -lz -lm

	(make log)

# make

/usr/bin/ld: cannot find -lgcc_eh

	Of course the commands all work on the command line.
	This is with gcc3/buildlink2.mk included in the Makefile - the
	failure mode is the same without.

	    .if defined(USE_GCC3)
	    .include "../../lang/gcc3/buildlink2.mk"
	    .endif
