The compiler machinery that generates "map.zero" symbols marks them as RODATA and DUPOK, which is problematic when a given application has multiple map zero symbols (from different packages) with varying sizes: the dupok path in the loader assumes that if two symbols have the same name, it is safe to pick any of the versions. In the case of map.zero, the link needs to select the largest symbol, not an arbitrary sym. To fix this problem, mark map.zero symbols as content-addressable, since the loader's content addressability processing path already supports selection of the larger symbol in cases where there are dups. Fixes #46653.
