See how libgcc_s is installed using the SHLIB_INSTALL macro (defined in libgcc/config/t-slibgcc). In fact, with the right substitutions you should be able to use that macro directly without writing your own (you need to subst @shlib_base_name@, @multilib_dir@ and @shlib_slibdir_qual@). > 3) I added t-libgcov t-libgcov-gld t-libgcov-elf-ver into *-linux for now.

I don't think you should need any? Also for linking you probably should be able to reuse the SHLIB_LINK macro (maybe a bit extending it is required). Ciao, Michael.
