AC_CHECK_FILE does not work in cross builds. Such builds aborted.
Replace it by AC_CHECK_HEADERS. This fixes cross builds.
To enable TensorFlow in cross builds, more work is needed.

This looks for one of the header files which are included by Tesseract.
It currently uses a hard coded path which works for Debian / Ubuntu.
Simplify also the rules for linking Tensorflow.

It expects include files in /usr/include/tensorflow.
* Add configure option --with-tensorflow (disabled by default)
* Fix data type tensorflow::int64
* Remove "third_party/" in include statements
* Add dummy implementations for Backward and DebugWeights in TFNetwork
* Add files generated with protoc from tfnetwork.proto
(so the Tensorflow sources are not needed for the build)
* Update Makefiles

Reduce the maximum message size from 64 KiB to 2 KiB which still should
be large enought for trace messages.
Create the smaller message on the stack instead of using a global
array to allow reentrancy and to reduce the memory use of Tesseract.

It is defined for all platforms when math.h or cmath is included
after defining the macro _USE_MATH_DEFINES.
Define _USE_MATH_DEFINES before any include statement to make sure
that M_PI gets defined. It is not necessary to define it conditionally
only for Windows.
