It looks like this isn't necessary (in any tests I've done, it results in the global being described with no location or value in the imported side - while it's still fully described in the place it's imported from) & results in significant/pathological debug info growth to home these location-less global variable descriptions on the import side. This is a rather pressing/important issue to address - this regressed executable size for one example I'm looking at by 15%, object size is probably similar though I haven't measured it, and a 22x increase in the number of CUs in the cu_index in split DWARF DWP files, creating a similarly large regression in the time it takes llvm-symbolizer to run on such binaries.
