Make --disable-threads incompatible with including OCR
Tesseract requires threading, even though Ghostscript doesn't actually call any
of the parts of tesseract that use threading, there is no sensible way to
leave it out.
So, throw an error if --disable-threads is used when tesseract/leptonica is
present. The error includes a note to use "--without-tesseract" to avoid the
error.
Also, fix a typo from a03ce3d6a130c843cb4dd91b7e767706973b4e22
