No. Nobody knows how many programs rely upon current behaviour of this
function.

Coreutils already includes canonicalize_file_name() implementation for
non-glibc platforms, so we can create new function and reuse this code.
I'd like to know how does current "readlink -f" work on Solaris where
resolvepath(2)-based implementation is used.
I'll submit necessary changes to the code and testsuit a bit later.
