There seems to be an issue when using tramp and eshell at the same time
such that eshell is unable to find the binaries on the remote host and
execute them. I can reproduce this on multiple hosts as well as with
`emacs -Q`.

---
Lets `cd` to the host using tramp and run a few commands
```
~ $ cd /ssh:ubuntu@artifactory-stage.delphix.com:/

/ssh:ubuntu@artifactory-stage.delphix.com: $ pwd
/ssh:ubuntu@artifactory-stage.delphix.com:

/ssh:ubuntu@artifactory-stage.delphix.com: $ ls
/ssh:ubuntu@artifactory-stage.delphix.com:/bin
...
dd                  ls             ntfswipe       systemd-inhibit
```

So far so good. Using the eshell version of these commands seem to
work. Now what if we call the non-eshell version?

```
/ssh:ubuntu@artifactory-stage.delphix.com: $ *ls
env: ‘/bin/ls’: No such file or directory
```

It seems like `ls` cannot be found but we just saw that it existed when
we ran `eshell/ls`. This problem continues with _any_ executable:

```
/ssh:ubuntu@artifactory-stage.delphix.com: $ *pwd
env: ‘/bin/pwd’: No such file or directory

/ssh:ubuntu@artifactory-stage.delphix.com: $ docker ps
env: ‘/usr/bin/docker’: No such file or directory
```

My version of tramp is: "2.7.0-pre"

Thanks for the report. This is already fixed on master (and the release 
branch) in 2af092741e54af6bf3bde62cff370853aab46745. Can you try 
updating to a more-recent revision?

Thank you for the incredibly quick response! Using the latest version of
Emacs resolved this for me

This seems to have been left open by accident, so I'm closing it now.
