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.
