The seccomp filters are currently built for the build host, not for the machine that they are going to run on, but they are also built for with the -m32 flag if the kernel is built for a 32 bit machine, both of which seems rather odd. It broke allyesconfig on my machine, which is x86-64, but building for 32 bit ARM, with this error message: In file included from /usr/include/stdio.h:28:0, from samples/seccomp/bpf-fancy.c:15: /usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory because there are no 32 bit libc headers installed on this machine. We should really be building all the samples for the target machine rather than the build host, but since the infrastructure for that appears to be missing right now, let's be a little bit smarter and not pass the '-m32' flag to the HOSTCC when cross- compiling.
