Replace prjxray-config by static configuration

[amibranch]

I was trying to package f4pga for arch-linux, by the following PKGBUILD: https://aur.archlinux.org/packages/f4pga-git

However, after installation, f4pga will not start, as it complains that prjxray-config cannot be found:

Traceback (most recent call last):

It took me some time to find prjxray-config, as it remained unclear to me what this should do or to which project it belongs. However, eventually I stumbled across it in a different package.

Is it possible to replace this script entirely by, e.g. a static config that will be created during the packaging of f4pga? IMO, the path that is returned by prjxray-config should not be returned by an executable, but configured by the packager during creation of the package?

If not, could this script just be created and packaged within the wheel of f4pga to avoid such problems?
