My hypothetical situation is a system not using glibc (e.g. based on
musl or uClibc) where someone is installing glibc under
/usr/glibc-compat (or whatever prefix you like) and is using an
appropriately-configured /lib/ld-linux.so.2 (or whatever name glibc
uses on that arch) that will search this path rather than the main
system paths. I see no reason such a setup should not work.
