There's no such parameter. Do you mean 'extra-lib-conditional' variable in
init-unix? If yes, commented as attached.

If you mean the 'condition' parameter to init-unix, this is meant to allow one
to specify specific condition under which the configured version of Python
will be used. So that you can configure two python versions which will be
used for different build properties, just like alternatives mechanism allow.
I don't remember exactly why it was added, either building 32 and 64-bit
tests, or something like that.

Originally meant so that you can configure Python differently for cygwin and
native windows compilers. Essentially the same as condition to 'init-unix',
but never tested.
