dh_installdocs --link-doc not allowed between arch dep & arch indep?

[أحمد المحمودي <aelmahmoudy@users.sourceforge.net>]

Hello

The package pcb builds 2 arch. dependent packages (pcb-gtk & pcb-lesstif) and an arch independent package (pcb-common) which contains data and documentation. Hence the arch. dependent packages depend on this arch independent package. 

Previously I ran:
dh_installdocs --link-doc=pcb-common 

which worked fine, yet after updating to compat level  10, I get the build error:

dh_installdocs: --link-doc not allowed between pcb-gtk and pcb-common (one is arch:all and the other not)

I checked the manpage which mentions that a link from arch. dependent to arch. independent will not work, what is the reason for this? Especially that my use case seems very sensible. Is there a workaround? 

Please reply me directly since I am not subscribed to the list.
