no, i don't think that's it:

(gdb) b printf
Function "printf" not defined.
Make breakpoint pending on future shared library load? (y or [n]) n

gdb is pretty smart about this....

we used to have problems stepping into shared lib functions before they
have been resolved by the loader, but this has been fixed some time
back.
