Well, the point of the feature test is not to pick up an external
definition of strlcpy(), but to keep working on systems where strcpy() has
been patched into _glibc_, where we cannot avoid linking to it. (ARCH
Linux is such a distribution for example.)
So it's a quirk in essence - and I think marking our implementation as
__weak ought to solve that.
