Try defining LLD_UNSAFE=yes in port's Makefile. It'd be translated to
LDFLAGS+=-fuse-ld=bfd and then by USES=cmake into
-DCMAKE_EXE_LINKER_FLAGS:STRING="${LDFLAGS}" \
-DCMAKE_MODULE_LINKER_FLAGS:STRING="${LDFLAGS}" \
-DCMAKE_SHARED_LINKER_FLAGS:STRING="${LDFLAGS}" \
$ make -V CMAKE_ARGS:M\*bfd\* LLD_UNSAFE=
-DCMAKE_EXE_LINKER_FLAGS:STRING=" -fstack-protector-strong -fuse-ld=bfd " -DCMAKE_MODULE_LINKER_FLAGS:STRING=" -fstack-protector-strong -fuse-ld=bfd " -DCMAKE_SHARED_LINKER_FLAGS:STRING=" -fstack-protector-strong -fuse-ld=bfd "
However, if you need /usr/local/bin/ld.bfd rather than /usr/bin/ld.bfd
on FreeBSD 11.* define USE_BINUTILS and pass LDFLAGS+=-B${LOCALBASE}/bin .
