Subject: [PATCH] parisc: Use secure_computing_strict, not secure_computing

After commit a4412fc9486e, the secure_computing function is only
available if seccomp filters are implemented by the architecture.
Architectures without seccomp filters use secure_computing_strict
instead.

This is minimally tested because my cross-compiler toolchain for parisc
is quite broken.  ptrace.c seems to *compile*, but it doesn't assemble.
