	(which describes the system on which I used send-pr and nothing at
	all related to the build or target environments, and so is a waste
	of space)
Architecture: x86_64
Machine: amd64
>Description:
	I am trying to do a fully static build to test whether there need
	to be mode adjustments to -lrumpxxx in various places to allow for
	-lrump now needing -lrumpvfs (where those libraries are handed to
	cc/ld as "-lrumpvfs -lrump" sometimes now - which works for .so
	libraries, but might not when using .a libraries.

	While doing such a build, I encountered...

#      link  dns-sd/dns-sd
/usr/obj/testing/tools/bin/x86_64--netbsd-gcc    --sysroot=/release/testing/amd64   -pie  -shared-libgcc  -Wl,-z,relro     -o dns-sd  dns-sd.o ClientCommon.o  -Wl,-rpath-link,/release/testing/amd64/lib  -L=/lib -ldns_sd

collect2: error: ld returned 1 exit status

*** Failed target:  dns-sd

	Dealing with gcc internal libraries, and crt*.o files is
	beyond my current knowledge, so I am hoping that someone
	else can look into that one.

	I have preseumed this to be a toolchain related issue, but
	feel free to reassign if appropriate.

>How-To-Repeat:
	build.sh -V MKPIC=no
