422452b9f4 Check for float errors when running tesseract and lstmtraining 
Some illegal floating point calculations like division by zero,
illegal value or overflow will now abort tesseract with an error
message.

For lstmtraining there is now a new parameter --debug_float to
enable the same kind of checks. It is currently disabled by default
because such errors occur and would abort the training process.
That should be fixed in the future.

If tesseract also shows floating point errors which cannot be
fixed easily, a similar parameter to enable the checks can be
added there, too.

The new code requires the function feenableexcept which is only
available with the GNU libc, so it is only used on Linux.
