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.
+* `--without-$app` - By default all applications in Erlang/OTP will be included
+ in a release. If this is not wanted it is possible to specify that Erlang/OTP
+ should be compiled without that applications, i.e. `--without-wx`. There is
+ no automatic dependency handling inbetween applications. So if you disable
+ an application that another depends on, you also have to disable the
+ dependant application.
If you or your system has special requirements please read the `Makefile` for
additional configuration information.
