bashism in configure script

[Zugschlus]

This is Debian Bug #998766, filed by Andrej Shadura

Your package uses configure script with bash features not present in
POSIX without explicitly declaring the need to bash shell; this
currently works as configure scripts select bash, but when dash enables
LINENO support, your configure script will start failing:

 ../configure: 7171: test: yes: unexpected operator

 checking that generated files are newer than configure... done                           

To test this, you can install dash from experimental and re-run the
configure script.

Please replace non-POSIX features with their equivalents to make sure
the script runs with dash. Most common ones are usage of == instead of =
and for with arrays (not lists).
