I'm jumping back to this very old thread. Could you explain (perhaps
re-explain) what you're trying to do ?

If you need to just re-run a specific step of a specific package, why
don't you use "make foo-build", "make foo-rebuild", etc. ?

It seems very hackish to extract the commands that Buildroot executes
to execute them outside the context of Buildroot. This doesn't really
help to make a case for accepting a patch like you're proposing. Could
you first convince us that there is a valid and reasonable use-case,
and then we can discuss how to support this use-case with Buildroot.

Best regards,

Thomas
