Erlang can be built without threads support, by passing an
appropriate config option.
This commit drops the config dependency on BR2_TOOLCHAIN_HAS_THREADS
and instead passes --disable-threads if the toolchain doesn't support
threads.
While here, change the wording of the config comment to "dynamic
library" to be consistent with similar comments elsewhere.

If the pcre package is build before erlang, the erlang's build
system use pcre.h from pcre package instead of using pcre.h bundled
by Erlang.
Erlang use an old version of this file which is incompatible
with the upstream one.

Packages that depend on Erlang may need the Erlang Interface Version
(aka EI_VSN), so just export it.
We do export a static value instead of looking in the file, to avoid
spawning a shell every time the variable is dereferenced.

The comment was missing the dependency on BR2_USE_MMU, and was using
'depends on !BR2_TOOLCHAIN_HAS_THREADS && BR2_STATIC_LIBS' while it
should in fact be '!BR2_TOOLCHAIN_HAS_THREADS || BR2_STATIC_LIBS',
since we want show the comment *either* when we don't have threads
*or* when we are building a purely static lib system.

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.

Erlang/OTP 17.4 is a service release on the 17 track with mostly bug
fixes, but it does contain a number of new features and characteristics
improvements as well.
Some highlights of the release are:
- eldap: Nearly all TCP options are possible to give in the
eldap:open/2 call.
- ssh: Added API functions ptty_alloc/3 and ptty_alloc/4, to allocate a
pseudo tty.
- ssl: Handle servers that may send an empty SNI extension to the client.

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.

Erlang uses openssl for all things crypto.
Since there are host Erlang tools that use crypto (such as rebar), we
need to build host-erlang with support for crypto, and thus it shall
depends on openssl.

OTP R16B03-1 is a service release which corrects a few issues found in
the R16B03 release. The corrections are:
- 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
Ramine)
- wx - Solved a problem which caused the debugger to crash when closing a
window. Fixed static linking on Mac.
- xmerl - Fixed a problem in the SAX-parser when the header of the next
document was appearing in the buffer when using the
xmerl_sax_parser:stream/2 function.
