+! after FIR is translated, so -emit-hlfir and -emit-fir cannot observe them.
+! -fno-plt marks an external procedure and a compiler runtime call nonlazybind
+! and requests GOT for compiler-rt. A procedure defined in this file, and an
+! intrinsic, are left unchanged. The default does neither.

Agree. I will relax the group check so that it requires nonlazybind without
requiring it to be the only attribute.
