Maybe "semi-automatically"... ;)

clive@akira:~/temp$ tinycc/tcc -v
tcc version 0.9.27 - b5d4b90 (x86_64 Linux)
clive@akira:~/temp$ cat b.c
int b(int x)
{
    float y = x;
    -y; /* generates the reference to __mzerosf */
    return y;
}
clive@akira:~/temp$ tinycc/tcc -c b.c
clive@akira:~/temp$ nm b.o
0000000000000000 T b
                 U __mzerosf
clive@akira:~/temp$ gcc -shared -o b.so b.o
clive@akira:~/temp$ ./a
./b.so: undefined symbol: __mzerosf

But I also got the OP's error with tcc:

clive@akira:~/temp$ tinycc/tcc -shared -o b.so b.c
clive@akira:~/temp$ ./a
./b.so: undefined symbol: __mzerosf
