Rework compile (#3124)

* DEBUG code

* make M=scripts clean before creating the package

Move the cleanup of the scripts target from the postinst script
to the logically correct place so that the cleanup occurs with
the same arguments of the make command and the same compiler.

* clear all files in target directory

* Debugging for version 5.10.10 and higher

* Return to version 5.12

Since version 5.12, there are no collisions
with deleting the scripts/module.lds file.

This pathology begins with 5.10 and ends on 5.11 inclusive,
and this is due to internal migration in the core.

* Change the order of creating packages

The linux-headers package must be built in the last queue

* Revert "DEBUG code"

This reverts commit 6bd8dca.
