Merge branch 'rickard/info/OTP-11196' into maint
* rickard/info/OTP-11196: Add test cases for native atomics and jump table Refuse to build SMP runtime by default without native atomics Make information about use of jump table available via system_info BIF Make ethread library information available via system_info BIF Make emulator arguments available via the system_info BIF

implementation available, you typically want to try using the
`libatomic_ops` library. It can be downloaded from
<http://www.hpl.hp.com/research/linux/atomic_ops/>.
+* `--disable-smp-require-native-atomics` - By default `configure` will
+ fail if an SMP runtime system is about to be built, and no implementation
+ for native atomic memory accesses can be found. If this happens, you are
+ encouraged to find a native atomic implementation that can be used, e.g.,
+ using `libatomic_ops`, but by passing `--disable-smp-require-native-atomics`
+ you can build using a fallback implementation based on mutexes or spinlocks.
+ Performance of the SMP runtime system will however suffer immensely without
+ an implementation for native atomic memory accesses.
If you or your system has special requirements please read the `Makefile` for
additional configuration information.
