That's the problem. It does not return the string associated with the
target errno, but something else.

But strerror interprets its argument as the host's errno value. If
host_to_target_error maps ELOOP to TARGET_ELOOP, and TARGET_ELOOP
happens have be the same value as EBADFD, the function wil return
"Bad file descriptor" instead of "Too many levels of symbolic links".
