configure: Fix incorrect string comparison operator

In commit c97d6d2cdf97ed we accidentally added code to configure
that uses '==' for string equality testing. This is a bashism --
the portable way to write this is '='.

This fixes the "Unexpected operator error" complaint produced
if the system /bin/sh is dash.
