It doesn't need to, the calls are emitted directly by the front-end (otherwise,
we'd be OK, as the library is in C and we do include <math.h>).
(As a sidenote, there is one minor thing for which recompiling libgfortran is
needed, and that's specific functions; I'm not using them here. Specific
functions are Fortran wrappers to math builtins that are compiled into
libgfortran and used when a Fortran intrinsic math function is passed as an
argument to another function.)

Of course, you're right, I got confused. It works:
$ ./bin/gcc -c s.c -mmacosx-version-min=10.3.9
$ nm s.o | grep printf
U _printf$LDBL128
$ ./bin/gcc -c s.c -mmacosx-version-min=10.3.8
$ nm s.o | grep printf
U _printf
