Looks like it. I tried an amd64 context (that was built using
WITH_LLD_IS_LD= in case that matters) and ports-mgmt/synth's
indirect build of lang/gcc6-aux quickly stopped for:

configure:4439: /usr/obj/portswork/usr/ports/lang/gcc6-aux/work/bootstrap/bin/gcc -O2 -pipe  -g -fstack-protector -fno-strict-aliasing -I/usr/local/include  -L/usr/local/lib -fstack-protector conftest.c  >&5
/usr/bin/ld: error: unable to find library -lssp_nonshared
/usr/bin/ld: error: unable to find library -lc
collect2: error: ld returned 1 exit status
configure:4443: $? = 1
configure:4480: result:

|   return 0;
| }
configure:4486: error: in `/usr/obj/portswork/usr/ports/lang/gcc6-aux/work/build':
configure:4490: error: C compiler cannot create executables

This happened even if I checked off in gcc6-aux's config
to do a bootstrap.

Even amd64 has build problems (at least for use of the
modern/experimental ld).
