Just for another data point, on 64 bit linux running ISE 11.4, I
pulled directly from git, did "touch <...>/coregen/*", and make proj,
make synth, then make bin in u2_rev3, and got a bit file okay.  Bitgen
gave an info message about the Match_cycle change, but otherwise just
normal warnings about dangling ram pins and built the bit file just
fine (although I haven't actually tested it on the usrp2 yet).
There were some warnings about deprecated options in the project early
on, but they seemed more or less harmless.

I'm not sure how your coregen cores got regenerated.  ISE 11.4 has
fifo generator 5.3, while the .xco files in coregen/* are for version
4.3 (which is why I had to touch all those files so it wouldn't try to
rebuild them, but just use the existing .ngcs)
