That works for me.  You'll have to tell us what you did.

 $ gcc a.c b.c -ffunction-sections
 $ nm a.out | grep -i ' t '
00000000004005b0 t __do_global_ctors_aux
0000000000400430 t __do_global_dtors_aux
00000000004005a0 T __libc_csu_fini
0000000000400510 T __libc_csu_init
00000000004005e8 T _fini
0000000000400390 T _init
00000000004003e0 T _start
000000000040040c t call_gmon_start
