Is this a duplicate of issue #2334? All errors shown in your make output are in files which are not part of the Tesseract sources. Those files obviously are for the Intel architecture, so they should not be included by ARM toolchains. This looks like a wrong build setting.

I don’t know whether the CMake build settings work for non Intel architectures. I know that the autoconf based build works, so please use that.
