Reverse the sense of EXPORT_SYMS. If EXPORT_SYMS is not
defined, no symbols are exported from the module. This is
the typical configuration for most device drivers and
standalone modules; only infrastructure modules or those with
special requirements typically need to export symbols.
Don't print the objcopy commands as they are run when converting
symbols; they're bulky and annoying in many cases.
