Actually dpkg-shlibdeps does not look at these linker script file, i.e. *.ver 
files in our case.

I must admit that, having maintaining a track in which particular version a 
given symbol has been introduced, is a compelling reason to resurrect the 
symbol files support once again, this would help build rdeps. 

OTOH, there used to be some private symbols leaked with our former set of 
symbols file (a great part due to my own fault), but now with the linker script 
introduced upstream few months ago, we can have the symbol files well sorted 
out.

I'll have a look once again at that too.
