Replace the line (for MINGW64)

  Libs: -L${libdir} -ltesseract -LD:/msys64/mingw64/lib -larchive -LD:/msys64/mingw64/lib -lcurl

by

  Libs: -L${libdir} -ltesseract -L/mingw64/lib -larchive -L/mingw64/lib -lcurl

* mingw-w64-tesseract-ocr/PKGBUILD:
  - replace absolute Windows paths in line of .pc file starting with
    'Libs:' by absolute Unix paths.
  - remove references to patch 001-proper-include-thread.patch having no
    effect.
* mingw-w64-tesseract-ocr/001-proper-include-thread.patch:
