This is a copy of projects/tesseract-ocr/build.sh including its history from

It allows maintaining the build rules with the Tesseract source code.
The build rules for Leptonica were slightly modified to avoid

- Replace AVX_OPT, AVX2_OPT, FMA_OPT, SSE41_OPT
- Replace AVX, AVX2, FMA, SSE4_1
- Write new HAVE_AVX, HAVE_AVX2, HAVE_FMA, HAVE_SSE4_1 into config_auto.h
- Put related conditionals in Makefile.am in one place
This makes the code clearer and fixes a log message in
IntSimdMatrixTest.AVX2.

Many tests have preconditions like a correct version of the test submodule
or installed traineddata files at the right location. They fail or even
crash if those preconditions are not met.

tessdata/eng.traineddata is missing.
