gen/genlib/cdc/gearbox: fix possible pointers overlap by removing AsyncResetSynchronizers.
...
read/write clocks don't have the same frequencies, using AsyncResetSynchronizers cause differents delay when releasing reset and can cause pointers overlap.

Add Diamond toolchain support for Linux.
...
This tries to replicate the same setup as in the Windows buildsystem. We
also remove the Jedecgen step, as it doesn't seem to be supported nor
necessary in newer versions of Diamond.

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 {}
