I would like to point to https://codereview.qt-project.org/#change,72361
which reduces the memory while linking by eliminating duplicate symbols in the 
dwarf2 or dwarf4 tables. It also instructs the gnu linker to use a slower O(n)  
table instead of the default O(n*log(n)) table.

Perhaps Debian can try that patch and gives us feedback?
