There were two issues.
First is related on ISPC's CMake configuration forcing C and C++
compilers to be clang and clang++. This goes against of desired
behavior when we use our own compiled clang compilers.
The second issue was related on linker failure: CLang libraries
are linked statically, and they need some of C++ 11 STL symbols
which are coming from libstdc++.

Set of fixes which had to be made in order to have dependencies built
on own laptop:
- Require bison as a dependent software. It is required by ISPC.
On macOS it is required to be installed via Homebrew. This is because
Bison from Xcode toolchain is too old.
- Made sure Boost is compiled using clang.
Without this gcc was used, and some unsupported command line argument
was passed to it.
- Modify OGG in a way which does in fact pull fixed sized types.
They are defined in stdint.h.
Without this fix FFmpeg will not detect presence of OGG because the
test program fails to compile.
- Force disable zstd compression and make wepb optional for the TIFF
library. Without this TIFF might pick up development libraries from
Homebrew.

This requires ISPC for building OpenImageDenoise, so that is now added as
a dependency as well. Blender itself does not need ISPC for building so it
is not included as part of the precompiled libraries.
