net-misc/openssh: disable problematic -fzero-call-used-regs=*
--with-hardening adds the following in addition to flags we
already set in our toolchain:
* -ftrapv (which is broken with GCC anyway),
* -ftrivial-auto-var-init=zero (which is nice, but not the end of
the world to not have)
* -fzero-call-used-regs=used (history of miscompilations with
Clang (bug #872548), ICEs on m68k (bug #920350, gcc PR113086,
gcc PR104820, gcc PR104817, gcc PR110934)).
Furthermore, OSSH_CHECK_CFLAG_COMPILE does not use AC_CACHE_CHECK,
so we cannot just disable -fzero-call-used-regs=used.
Therefore, just pass --without-hardening, given it doesn't negate
our already hardened toolchain defaults, and avoids adding flags
which are known-broken in both Clang and GCC and haven't been
proven reliable.
