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.
This directory contains the source code for the architecture-dependent
files that go in ${archlibdir}. At present, these are mostly utility
programs used by GNU Emacs.
