libtool don't compile Fortran to shared library - fortran

Question

I need to use libtool to compile a Fortran library, because I need the static and shared version, but the compilation won't work in the same way of a C library.
In the case of a C library:
$ cat hello.c
#include <stdio.h>
int hello() {
printf("Hello\n");
return 0;
}
$ libtool --tag=CC --mode=compile gcc -c hello.c
libtool: compile: gcc -c hello.c -fPIC -DPIC -o .libs/hello.o
libtool: compile: gcc -c hello.c -o hello.o >/dev/null 2>&1
$ nm .libs/hello.o
U _GLOBAL_OFFSET_TABLE_
0000000000000000 T hello
U puts
As you can see in the example above libtool has add the -fPIC and the object has the _GLOBAL_OFFSET_TABLE_.
In the case of a Fortran library:
$ cat hello.f
function hello ()
write (*,*) "Hello"
endfunction hello
$ libtool --tag=FC --mode=compile gfortran -c hello.f
libtool: compile: gfortran -c hello.f -o .libs/hello.o
libtool: compile: gfortran -c hello.f >/dev/null 2>&1
$ nm .libs/hello.o
U _gfortran_st_write
U _gfortran_st_write_done
U _gfortran_transfer_character_write
0000000000000000 T hello_
As you can see in the example above libtool hasn't add the -fPIC and the object hasn't the _GLOBAL_OFFSET_TABLE_.
How can I solve this problem?
Additional information

You can also just use gcc
> libtool --tag=FC --mode=compile gcc -c hello.f90
libtool: compile: gcc -c hello.f90 -fPIC -o .libs/hello.o
libtool: compile: gcc -c hello.f90 -o hello.o >/dev/null 2>&1
> nm .libs/hello.o
U _gfortran_st_write
U _gfortran_st_write_done
U _gfortran_transfer_character_write
U _GLOBAL_OFFSET_TABLE_
0000000000000000 T hello_
