Followup of 07160a23fa2, 9e006e94c9c, 8fd49c4d8e9, d9d012965de. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=58332 rr-debugger-Bug: https://github.com/rr-debugger/rr/issues/3972 Since above commits Wine uses for some mappings at Linux MAP_PRIVATE. Unfortunately this is not fully supported by rr, at least with the flags for the session mapping. And if I understood it correctly, adding support in rr would come with a general performance penalty. Probably we can use the fallback path of non-linux systems for rr, too? This patch should not change behaviour, except for session mapping when running below rr, which is detected by the environment `RUNNING_UNDER_RR`. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10925
