This is on an x86_64 machine with 32 bit userspace.
AFAICS, the problem is that lib-src/seccomp-filter.c (line 173) tests
for a 64 bit userspace:
verify (sizeof (long) == 8 && LONG_MIN == INT64_MIN
&& LONG_MAX == INT64_MAX);
However, lib_src/Makefile.in (line 203) tests for 64 bit hardware:
ifeq ($(shell uname -m),x86_64)
[...]
SECCOMP_FILTER=1
endif

Thanks for the report. Is there a good way to test for a 64-bit
userspace? Probably we want both tests.

I've now tried fixing this with commit db259d8fd369e6036df782d5fe51723a68220074.

Autoconf has AC_CHECK_SIZEOF, so you could check for the size of either
long or void *.

Thank you, this fixes the problem for me.
I have tested it on the same system where the bug was originally seen.
This is an amd64 system with 64 bit kernel but 32 bit userspace:
In GNU Emacs 28.1.90 (build 1, i686-pc-linux-gnu)
