As Tomas said, this error is emitted by the linker, not by our
compiler. The compiler, unless with an internal linker, is completely
oblivious to which libraries you have or don't have. And with good
reason: it shouldn't have to know anything about that, since those
are the linker's domain. Separation of concerns.

But the result is useless without Valgrind (no more useful than a
regularly compiled binary at least), just like compiling with -gd is
useless without the gprof. It's just a cosmetic difference; in
principle it's exactly the same thing.
