[PATCH v2 2/2] kbuild: deb-pkg: split debian/rules

From: Masahiro Yamada
Date: Tue Aug 01 2023 - 08:19:38 EST


debian/rules is generated by shell, but the escape sequence (\$) is
unreadable.

debian/rules embeds only two variables (ARCH and KERNELRELEASE).

Split them out to debian/rules.vars, and check-in the rest of Makefile
code to scripts/package/debian/rules.

Changes in v2:
- Change ${MAKE} to $(MAKE) for consistency
- Fix shellcheck warning
