[OE-core] [PATCHv4 0/6] Add dummy tools to help identify needed dependencies

[Peter Kjellerstedt]

After the introduction of RSS, I still found it hard to get
dependencies on some common tools that are typically installed on the
build host correct. Using the wrong version of tools like pkg-config,
gdbus-codegen and dbus-binding-tool can cause build failures.

To circumvent this, I created dummy versions of the tools that always
fail and placed them in the scripts directory. Thus, if the real tool
has not been installed in the RSS, the dummy version is used and the
build fails. For good measures I even output a message that says what
needs to be corrected in the recipe.

Included is also an update to linux-libc-headers as it apparently
needs to inherit pkgconfig, which the introduction of the dummy
version of pkg-config showed.

PATCHv2: Also inherit pkgconfig in module.bbclass since pkg-config
is needed for the make_scripts task.

PATCHv3: Add a missing Signed-off-by footer.

PATCHv4: Move the dummy scripts to scripts/blacklisted and add it to
PATH in bitbake.conf.
