As seen in strace bash already checks for existance of the script and the
#!interpreter. So when execve threw a ENOENT ("The file filename or a script
or ELF interpreter does not exist, or a shared library needed for file or
interpreter cannot be found.") it could at least say something like
"interpreter or libs not found, try ldd for debugging".
