[bitbake-devel] [PATCH] build.py: warn of deprecated use of [noexec] or [nostamp] with value other than '1'

[Chris Laplante]

It would be nice for something like the following to work:

    do_task[noexec] = "${@"1" if condition else ""}"

It currently does not, because "noexec" takes effect even when the flag
is present but the value is "".
