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
