selftests/x86: Do not rely on "int $0x80" in single_step_syscall.c
commit 4105c69703cdeba76f384b901712c9397b04e9c2 upstream.
On 64-bit builds, we should not rely on "int $0x80" working (it only does if
CONFIG_IA32_EMULATION=y is enabled). To keep the "Set TF and check int80"
test running on 64-bit installs with CONFIG_IA32_EMULATION=y enabled, build
this test only if we can also build 32-bit binaries (which should be a
good approximation for that).
