[tor/master] Quotes added on configure script's string comparison.
commit 44ea7af6860a069435b264f5fe5eea0123ab7d97 Author: zerosion <zerosion@protonmail.ch> Date: Thu Feb 4 02:28:38 2016 +0100 Quotes added on configure script's string comparison. Solves #17744 The syntax has been generalized too, so there are only double quotes.
