FYI, this is what Mandriva (back then), now Mageia and OpenMandriva, have been doing for years (and still do). https://wiki.mageia.org/en/Overlinking_issues_in_packaging > As long as I've done many times full recompilation on the scale of whole > distribution in the past I know that sometimes is necessary to add small > linker fix when library X is linked with other libraries A and B and only > A is used and linked executable is using libX and libB ABI but has no -lB > in linker options, but majority of those changes have been already merged > to most of the packages source trees. Indeed, the folks involved in the Mandriva --as-needed migration reported that the effort required was similar to the one for the "no more transitive linking" change https://fedoraproject.org/wiki/Features/ChangeInImplicitDSOLinking in Fedora (since Fedora 13) that you are alluding to.
