Subject: Only attempt to generate seccomp filter files on x86-64 systems.
X-Git-Tag: emacs-28.0.90~2908
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9dc26d4a8add5b3f2a5fce7907af4f9673ae82c0;p=emacs.git

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.
