It's a complicated mumble-jumble. Prior art exists as in: /opt/vendorThing/bin/... /usr/X11R6/lib/libXi.so.6 [host binary] /usr/x86_64-w64-mingw32/bin/as [host binary] /usr/x86_64-w64-mingw32/sys-root/mingw/bin/as.exe [foreign binary] /usr/platform/SUNW,Ultra-2/lib/libprtdiag_psr.so.1 [looks foreign] The use of suffix-based naming must have been established sometime near the end of the 90s or the start of 2000s as the first biarch Linux distros emerged. Probably in gcc or glibc sources one will find the root of where the use of suffix identifiers like /usr/lib64 started. Leaves the question open "why".
