It's not a bug in our build system; it's a bug in Gentoo's library set,
ie, the heimdal library is exposing a symbol that it can't actually
guarantee to provide. If it were a generic issue we'd be seeing it
reported on other Linuxen, since AFAIK nobody's glibc provides strlcpy.
The question for us is whether we should install a workaround, which in
any case would only be needed until Gentoo fixes their heimdal build.
I'm inclined to agree with Bruce that it's not worth the trouble ---
especially since I don't care for any of the solutions you proposed.
Most of them could break other platforms.
