vivado: Fix segfault with or1k.
...
The or1k doesn't have any verilog include paths added. This means the
code use to generate;
```tcl
synth_design -top top -part xc7a50t-csg325-2 -include_dirs {}
```
which causes Vivado to segfault with the following error;
```
Command: synth_design -top top -part xc7a50t-csg325-2 -include_dirs {}
