Make ffmpeg static again and fix Linux build in general.

Zalewa commented 6 years ago

Use $TARGET_DIR, not /usr/local, as prefix in Linux builds of OpenSSL and zlib. This problem was not affecting Docker builds because you have root rights there, but building outside Docker was no longer possible.
ffmpeg --extra-ldexeflags '-static' is vital in getting an actually static build. '-Bstatic' is for something else and was useless in this context.
librtmp now needs to include openssl/ssl.h from $TARGET_DIR/include path. "INC=" entry is added to the Makefile.
Disable x265 CLI target because it is not needed.
x265.pc: -lgcc_s must be replaced with -lgcc_eh. Unfortunately, due to how x265 CMakeLists.txt is constructed, this cannot be done in any other way than just replacing it with 'sed' after the file has been already created.

Thanks, good stuff.

Do you mind picking the changes from #63 as well so this won't happen again?

Zalewa commented 6 years ago

@zimbatm Okay, I'll take a look at that. I spent whole day working on this fix and I don't want a repeat of that either :).

@zimbatm Travis CI is done and done. Could you please merge this?
