The non-SMP scheduler was deprecated with the Erlang/OTP 20.0 release and
slated for removal with the next major Erlang release. Since the non-SMP
scheduler isn't even built anymore, this option no longer has the
intended effect of saving space or compile time. The SMP scheduler
supports both SMP and non-SMP processors, so removing the option will
not break any platforms.
We do not need to add a legacy entry, because the new behavior is the
same as with the option previously set (i.e. SMP enabled).

For some platforms, hardware-assisted compare-and-swap may not be
available, so libatomic_ops will not provide it.
However, libatomic_ops can provide a purely software CAS emulation, but
must be instructed to do so. erlang just forgot to tell libatomic_ops
that it does require CAS.
Fix that by defining AO_REQUIRE_CAS before including atmoic_ops.h, like
is done in libunwind, as pointed out by Thomas.
Also, erlang has a convoluted, mind-alterating set on aclocal.m4 macros,
that just forgets to link against -latomic_ops when checking CAS is
available, so that even if CAS is available, configure chokes.
Since I would like to keep the little sanity I still have, just force
linking with -latomic_ops. This is useless when the check is natrally
sucessful (i.e. on platforms where CAS is available in HW), but we
would eventually link with -latomic_ops there, too; it's just redundant.
Overall, just consider that erlang requires libatomic_ops, so forcibly
depend on it, it is easier than trying to disable it. We can revisit
that whenever someone wants to run erlang on a platform for which there
is no libatomic_ops support.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

OTP R16B03-1 is a service release which corrects a few issues found in

- The ODBC application was missing in the prebuilt Windows installers
- 3 corrections in the SSL application:
- Add missing validation of the server_name_indication option and test for
its explicit use.
- Elliptic curve selection in server mode now properly selects a curve
suggested by the client, if possible.
- The server did not indicate support for secure renegotiation during TLS
extension handling.
- In the syntax tools application a bug was introduced which broke
reverting of local funs. This is now corrected (thanks to Anthony
