Your shell should handle this.  I'm not sure whether it's in the upstream bash (it should be) but I wrote a long, long time ago a patch which produces better messages.  On my system I get:

$ ./u
bash: ./u: /some/path/does-not-exist: bad ELF interpreter: No such file or directory

It doesn't really matter what the kernel returns.  The shell should do its job and at least the RHEL/Fedora version does it for a long time now.
