[Buildroot] [git commit branch/2018.11.x] libwebsock: Fix openssl reporting in header

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=f1f6b39438259a816cdeac792b30987dfd7b0970
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x

The websock_config.h file currently ends up being installed into the
sysroot with a #include "config.h" line but the config.h file does not
get copied into the sysroot. Refactoring the original patch to have the
configure script properly report whether or not SSL support is enabled
without using the config.h file.

Patch has been submitted upstream but may never be merged since upstream
appears to be dead.

 config: fix SSL detection
 
-The @WEBSOCK_HAVE_SSL@ is not replaced at configure time, and even if
-it was, it would be replaced by an empty string if openssl is disabled,
-thus still defining WEBSOCK_HAVE_SSL when we would not want it.
+The @WEBSOCK_HAVE_SSL@ is replaced at configure time with either a 1 or 0.
+The rest of the code is simply checking to see if WEBSOCK_HAVE_SSL is
+defined at all. Using a #undef WEBSOCK_HAVE_SSL will cause configure
+to either comment it out or change the line to
+"#define WEBSOCK_HAVE_SSL 1".
 
-Instead, rely on config.h, which is properly generated by ./configure,
-to provide the information about whether openssl is enabled or not.
