omxplayer: Update and add fixes for OpenSSL 1.1.x and thumb2

Browse Source 
* Update to latest from upstream
* Backport OpenSSL 1.1.x related patches for ffmpeg
* Pass --cpu based on machine, instead of hardcoding it to arm1176jzf-s
* Make --cc, --cxx and --ld be used from environment, helps building
  with clang
* It requires userland graphics driver to build to encode that in
  COMPATIBLE_HOST

Subject: [PATCH] rtmpdh: Stop using OpenSSL-provided DH functions to support
1.1.0
DH (struct dh_st) was made private in the 1.1 series, instead
DH is now done the same way as with gcrypt / libgmp.

If by 'apple based arm' you mean llvm/clang assembler, then yes, I've verified
that the assembly works with armv7a-cros-linux-gnueabi-clang (version 7.0.0).
Updated patch with new commit message is attached.
Thanks,
Rahul

Subject: [PATCH] swresample/arm: remove unintentional relocation.
Branch to global symbol results in reference to PLT, and when compiling
for THUMB-2 - in a R_ARM_THM_JUMP19 relocation. Some linkers don't
support this relocation (ld.gold), while others can end up truncating
the relocation to fit (ld.bfd).
Convert this branch through PLT into a direct branch that the assembler
can resolve locally.
See https://github.com/android-ndk/ndk/issues/337 for background.
The current workaround is to disable neon during gstreamer build,
which is not optimal and can be reverted after this patch:
https://github.com/freedesktop/gstreamer-cerbero/commit/41556c415739fbc3a72c7eaee7e70a565b719b2f
