We currently allow calling close() on the x32 architecture when we're
generating a blacklist filter for x86 and x86_64, i.e. one with an
ALLOW policy. We shouldn't as the default handling for unsupported
architectures should be defined by the bad_arch handling -- not the
default policy.
The reason for the faulty behaviour is the wrong jump target for the
x32 architecture test. It should jump to the KILL label, not the next
architecture test instruction. That one won't test the architecture
any more as the accumulator register was already overwritten with the
syscall number for the x32 test.
This test generates a filter that should return ERRNO(1) on calls to
close() for supported architectures or KILL on unsupported ones. But,
currently, does not do so for x32 and ALLOWs the syscall instead.
