Name libraries (dll/so) separately from linker symbols
Tracking ticket so I don't forget. Based on feedback on
#ghc, it sounds like it would be helpful if library names on the file system only had their full package name, e.g.
libHScontainers_HASH.so as opposed to the abbreviated package name. Additionally, it seems less necessary to provide the abbreviated package name in linker symbols, since the modules often give a pretty good clue (and the package key can be looked up.) So let's do this, and make things better for users.
