From the look of it, either your toolchain is mis-configured or
you're generating the wrong object format.
You should be seeing something like this (note lack of underscore):
/tmp/ccmb1952.o: In function `main':
/tmp/ccmb1952.o(.text+0xf): undefined reference to `printf'
I think you mentioned somewhere you're generating ELF (not a.out);
if so, your compiler is not doing the right thing for external
symbols. What appeared in FreeBSD a.out libraries as "_printf" is
plain "printf" in ELF. There is no "_printf" symbol in the standard
FreeBSD libc, nowadays.
