I did some more searching and I found this github issue with a workaround:
https://github.com/EttusResearch/uhd/issues/103
(begin quote):
I hit the same ddr3_32bit build error on Windows:
[IP_Flow 19-3475] Tcl error in ::ipgui_ddr3_32bit::updateAllModelParams
procedure for IP 'ddr3_32bit'. Loading device for application Rf_Device
from file '7k410t.nph' in environment
C:/Xilinx/Vivado/2015.4/ids_lite/ISE.
child killed: floating-point exception
Workaround I found is the following:
$ cd build-ip/xc7k410tffg900-2/ddr3_32bit/
$ rm mig_a.prj
$ cp mig_xc7k410tffg900-2.prj mig_a.prj
It looks like tcl does not like mig_a.prj being a link on Windows.
(end quote)
The build seems to successfully get past the mig however it fails on the
"pga" block (much later in the build process):
synth_ip: Time (s): cpu = 00:47:50 ; elapsed = 00:55:13 . Memory (MB): peak
= 1815.309 ; gain = 1479.445
BUILDER: Adding file from Block Design list: C:

I will switch over to the master branch if you think my time will be more
productive there? I saw that you are working toward a new release very soon.
