linking both executables and shared libraries, and we add on LDFLAGS_EX when linking executables or LDFLAGS_SL when linking shared libraries. This provides a significantly cleaner way of dealing with link-time switches than the former behavior. Also, make sure that the various platform-specific %.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that before. (I did not add these variables for the platforms that invoke $(LD) directly, however. It's not clear if we can do that safely, since for the most part we assume these variables use CC command-line syntax.) Per gripe from Aaron Swenson and subsequent investigation.
