Subject: [PATCH v4 4/7] selftest/x86: build both bitnesses

Using uname with the processor flag option in some cases can yield 'unknown'
so lets use the machine flag option as it is deterministic. Add a dependency
for all_32 when building on a x86 64 bit host so that both bitnesses are
built in this case.
