5e3665c6ae Remove most libtiff dependencies 
libtiff is no longer needed for OpenCL, so remove that dependency.

It is still suggested for Windows to redirect warning messages
from the tesseract executable to the console.

31cb732a0f opencl: Add missing TIFF library for macOS 
The OpenCL code of Tesseract uses TIFF functions, but the TIFF library
was not added to the linker flags for macOS.

This fixes builds with OpenCL on Mac.

b7ef3e0193 configure: Run AVX test only with 64 bit compiler 
The current implementation for AVX uses 64 bit code,
so run the AVX test only when the compiler is a 64 bit compiler.

This fixes the broken implementation for 32 bit hosts
which provide AVX but call the stub of DotProductAVX.

Simplify also the conditional code for AVX_OPT and SSE41_OPT.

6140be6a55 openmp: Fix build with clang++ and compilers without OpenMP support 
Builds without support for OpenMP failed with the old code. Fix this:

* Add OPENMP_CXXFLAGS for ccmain.
* Replace unconditional -fopenmp by OPENMP_CXXFLAGS for lstm.
* Always use _OPENMP for conditional compilation.
* Remove OPENMP as there is already _OPENMP.
* Include omp.h conditionally.

1b9d0688fa configure: Fix check for dependencies needed for training 
The different checks had set ENABLE_TRAINING unconditionally,
thus overwriting the value from the preceding checks.

So if pango and cairo were available, but icu was missing,
users would still be offered to build the training tools.

The changes for icu and has_cpp11 are not strictly necessary,
but are made here to have uniform code patterns.

included by autoconf the detection of the type will fail.  This type is
required by `unicharset_extractor` to autogenerate the character
properties.
