compiler{,-gcc4}.h, bug.h: Remove duplicate macros
__linktime_error() does the same thing as __compiletime_error() and is only used in bug.h. Since the macro defines a function attribute that will cause a failure at compile-time (not link-time), it makes more sense to keep __compiletime_error(), which is also neatly mated with __compiletime_warning().
