Unfortunately multiply defined weak symbols don't work like they're supposed to when the different versions are across dynamic linking boundaries. Fortunately, a weak symbol with no definition at all will still consistently evaluate as 0, and a singularly defined weak symbol will still resolve correctly. Instead of relying on a weak version of sc_main being overridden by a strong/non-default definition, this change leaves it as undefined and detects at run time whether the symbol resolves to 0 or to an actual code location.
