Check both in configure.ac (after checking if we need to rebuild

I'm ok with this patch (aka ack).
Just wanted to note that the condition is not accurate/sufficient, for example
pyparsing is also needed to build the server if generated* files are missing, or
if spice.proto is modified. Also if client/generated_marshallers.cpp does not
exist but server/generated* exist and only the server is being built, then there
is no need for pyparsing. However it probably covers most of "real" scenarios,
and is better than what we (don't) have today.
