master 9dc26d4: Only attempt to generate seccomp filter files on x86-64 systems.

[Philipp Stephani]

branch: master
commit 9dc26d4a8add5b3f2a5fce7907af4f9673ae82c0
Author: Philipp Stephani <phst@google.com>
Commit: Philipp Stephani <phst@google.com>

    Only attempt to generate seccomp filter files on x86-64 systems.
    
    The seccomp filters are always architecture-specific, and
    seccomp-filter.c right now only supports x86-64.
    
    * lib-src/Makefile.in (SECCOMP_FILTER): New variable.
    (DONT_INSTALL, all, seccomp-filter$(EXEEXT)): Use it.
