Currently we look to see if the main.main symbol address is in the module data text range. This requires access to the main.main symbol, which usually the runtime has, but does not when building a plugin. To avoid a dynamic relocation to main.main (which I haven't worked out how to have the linker generate on darwin), stop using the symbol. Instead record a boolean in the moduledata if the module has the main function.
