Graphviz is actually needed for building the docs I've found.

Specifically, copying the config.cache from base to both of the gtk{2,3}
builds should work, but not gtk2->3.  I've re-arranged the cygport file
to first configure all three (makes it easier to hunt for differences),
then build in reverse order.

That's odd.  I've built on a 4-core/8-thread Haswell in well under two
hours per architecture and I haven't seen memory peak above 8GiB.  You
said you are building in a VM, perhaps you should reduce the number of
threads there a bit.  If the VM starts contending for host resources
things _will_ get ugly.
