Warn to not add debug hook targets

Browse Source 
This adds a boiler-plate warning to the debug hooks structure to
strongly discourage people from adding new debug hook targets since

a DWARF view of debug in the middle-end and have support for alternate
output formats to be generated off that DWARF representation.
