Out of curiosity (I'm not saying it's a good idea!), do you know if FreeBSD's localedef can compile glibc's collation definitions? In theory they are in a format standardised by POSIX... I suspect there may be extensions and quirks... At a wild guess, since the data you showed doesn't even look like it contains non-ASCII characters (it looks like machine readable identifiers or something, and perhaps its the sort order of '-' that is causing you trouble), so it might also be possible to use "ucs_basic" locale for that column and then all computers will agree on the sort order, but of course that doesn't address the more general problem; presumably you might also have Russian language text in your system too. As for ".utf8" vs ".UTF-8", which one is selected by initdb as the database default seems to be something that varies between Linux distributions, so I guess maybe the installers use different techniques for discovering and selecting default locale names. Unlike glibc, FreeBSD doesn't do any name mangling at all when mapping LC_COLLATE to a pathname to find the file, whereas glibc downcases and removes '-' so you can find both formats of name in the various places...
