Comment:
The following would "fix" the default `PATH` in bash (to exclude `.`):

        rm -r ${DESTDIR}/usr/share/doc
```

It's not a very common situation to start bash with unset `PATH`, so this is not that important.

On the other hand, adding `-DSSH_SOURCE_BASAHRC` is IMHO very, very, necessary, and the only way (afaik) to have a reasonable bash startup that works fine with ssh (e.g. to setup `PATH`, etc).
