kbuild: add a phony target to run a command with Kbuild env vars
There are some cases where we want to run a command with the same
environment variables as Kbuild uses. For example, 'make coccicheck'
invokes scripts/coccicheck from the top Makefile so that the script can
reference to ${LINUXINCLUDE}, ${KBUILD_EXTMOD}, etc. The top Makefile
defines several phony targets that run a script.
We do it also for an internally used script, which results in a somewhat
complex call graph.
One example:
debian/rules binary-arch
-> make intdeb-pkg
-> scripts/package/builddeb
It is also tedious to add a dedicated target like 'intdeb-pkg' for each
use case.
Add a generic target 'run-command' to run an arbitrary command in an
environment with all Kbuild variables set.
The usage is:
$ make run-command KBUILD_RUN_COMMAND=<command>
The concept is similar to:
$ dpkg-architecture -c <command>
This executes <command> in an environment which has all DEB_* variables
defined.
Convert the existing 'make intdeb-pkg'.
Another possible usage is to interrogate a Make variable.
$ make run-command KBUILD_RUN_COMMAND='echo $(KBUILD_CFLAGS)'
might be useful to see KBUILD_CFLAGS set by the top Makefile.
