Build break on amd64 and evbmips

[Paul Goyette <paul%whooppee.com@localhost>]

On amd64, starting with a clean $OBJDIR I get

#     build  libatf-c++/libatf-c++.so.0.0
rm -f libatf-c++.so.0.0
/build/netbsd-local/tools/x86_64/amd64/bin/x86_64--netbsd-c++  -Wl,-x -shared -Wl,-soname,libatf-c++.so.0 -Wl,--warn-shared-textrel  --sysroot=/build/netbsd-local/dest/amd64   -o libatf-c++.so.0.0  -Wl,-rpath-link,/build/netbsd-local/dest/amd64/lib  -L=/lib  -Wl,--whole-archive libatf-c++_pic.a -Wl,--no-whole-archive -L/build/netbsd-local/obj/amd64/external/bsd/atf/lib/libatf-c++/../libatf-c -latf-c

On evbmips, I get

#     build  libatf-c++/libatf-c++.so.0.0
rm -f libatf-c++.so.0.0
/build/netbsd-local/tools/x86_64/mipseb-evbmips/bin/mipseb--netbsd-c++  -Wl,-x -shared -Wl,-soname,libatf-c++.so.0 -Wl,--warn-shared-textrel  --sysroot=/build/netbsd-local/dest/mipseb-evbmips   -o libatf-c++.so.0.0  -Wl,-rpath-link,/build/netbsd-local/dest/mipseb-evbmips/lib  -L=/lib  -Wl,--whole-archive libatf-c++.a -Wl,--no-whole-archive -L/build/netbsd-local/obj/mipseb-evbmips/external/bsd/atf/lib/libatf-c++/../libatf-c -latf-c
