A Tesseract binary with OpenCL support can also run on a host without
any OpenCL platform, as it simply uses the normal CPU based code.

Since commit 245eebdf29, Tesseract 3.05
requires Leptonica 1.74, so this is not a new requirement for 4.00.

Implement and contribute one small typographical fix, thereby improving the readability of the script's check
for the existence of the `m4` top-level directory.
Fix these kinds of warnings:
SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..' instead.
SC2086: Double quote to prevent globbing and word splitting.
SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.

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.

opencl_device_selection.h contains lots of code which is only used in
openclwrapper.cpp. This results in several compiler warnings:
opencl/opencl_device_selection.h:396:18: warning:
‘ds_status readProfileFromFile(ds_profile*, ds_score_deserializer, const char*)’ defined but not used [-Wunused-function]
opencl/opencl_device_selection.h:257:18: warning:
‘ds_status writeProfileToFile(ds_profile*, ds_score_serializer, const char*)’ defined but not used [-Wunused-function]
opencl/opencl_device_selection.h:196:18: warning:
‘ds_status profileDevices(ds_profile*, ds_evaluation_type, ds_perf_evaluator, void*, unsigned int*)’ defined but not used [-Wunused-function]
opencl/opencl_device_selection.h:90:18: warning:

opencl/opencl_device_selection.h:70:18: warning:
‘ds_status releaseDSProfile(ds_profile*, ds_score_release)’ defined but not used [-Wunused-function]
Move that functions and all related code to openclwrapper.cpp.

@zdenko Please change as you see fit.
My confusion is because, https://github.com/tesseract-ocr/tesseract/releases shows
on Nov 8, 2016
4.00.00alpha …
c1c1e42 zip tar.gz
If someone gets that zip/tar, it will not have all the items listed on Changelog for 4.0.0-alpha.
