I haven't tested i386 for a long time (after playing with some
openSUSE i586 image a couple of years ago). It turns out that a number
of system calls we actually need were denied by the seccomp filter,
and not even basic functionality works.
Add some system calls that glibc started using with the 64-bit time
("t64") transition, see also:
https://wiki.debian.org/ReleaseGoals/64bit-time
that is: clock_gettime64, timerfd_gettime64, fcntl64, and
recvmmsg_time64.
Add further system calls that are needed regardless of time_t width,
that is, mmap2 (valgrind profile only), _llseek and sigreturn (common
outside x86_64), and socketcall (same as s390x).
I validated this against an almost full run of the test suite, with
just a few selected tests skipped. Fixes needed to run most tests on
i386/i686, and other assorted fixes for tests, are included in
upcoming patches.
