The root cause is the port is performing strip for non-binary files at post-install target.
strip leaves temporary files named like sbin/ecp.fQXqex4S if it failed to strip. As a result, poudriere complains there's a orphaned file.
```
Error: Orphaned: sbin/ecp.fQXqex4S
```
And what is worse, actually binaries are not stripped at all. If even a single file fails to strip, all files are not stripped. In the following example, not only c.plaintext but {a,b,c}.binary are not stripped.
```
$ strip a.binary b.binary c.plaintext d.binary
```
I've changed post-install target to perform strip only for executables and shared libraries. Also pet the following poudrier warnings & errors.
```
