[task #15682] maneage-lint: check for host system shebang lines in executable scripts

[Boud Roukema]

Follow-up Comment #4, task #15682 (project reproduce):

[comment #3 comment #3:]

> The reason is that within the project's Make (as called in the top-level
'project' script) we completely close-off the host's environment and have our
own PATH. So 'env PROGNAME' should expand to the PROGNAME in Maneage, right?
Even if 'env' doesn't belong to Maneage itself.

I don't think that _expand_ is the right word; the effect is that the
environment variables from the environment are used. When running a make rule
from inside our .mk files, we have PATH=.local/bin . So the behaviour should
be something like this:


$ cat .local/bin/dummy
#!/usr/bin/env bash
printf "${BASH_VERSION}\n\n"

$ PATH=.local/bin dummy
5.0.11(1)-release

$ .local/bin/dummy
4.4.12(1)-release
