That matches my observation: on FreeBSD 9 (which is still installed on
my sparc64 box), I could successfully build zsh without problems.
Since the major difference from there to current FreeBSD/sparc64 is
the change of the compiler (GCC vs. Clang), this is also a strong
indication of undefined behaviour effects (I think).

Alas, my attempt to install FreeBSD 10.2 on a second disk on that
machine ended up with a kernel that stalled at mounting the root FS,
that's why I didn't investigate further by that time.
