Subject: [PATCH] linux/configure.ac: Fix tesseract conditional problem.

For tesseract-ocr's stock pkg-config, it would produce an error due to
unquoted whitespace:

  $ test ! -z `pkg-config --libs-only-l --silence-errors tesseract`
  bash: test: syntax error: `-larchive' unexpected

* linux/configure.ac: Use a positive test, and double-quote the $() command
substitution.
