We must write config.opt in the same directory we're reading it from.
We must not write the -top-level argument to config.opt.

Passing arguments with equal signs was broken for configure.bat and
qt-configure-module.bat. An argument FOO=BAR was split at = and written
as
FOO
BAR
to config.opt, breaking every attempt of assigning CMake variables.
We must not iterate over %* in batch files to avoid splitting arguments
at equal signs. Instead, pass %* unmodified to a CMake script that
writes config.opt.
