[cocci] [PATCH v2 04/11] kbuild: use 'output' variable to create the output directory

[Masahiro Yamada <masahiroy@kernel.org>]

$(KBUILD_OUTPUT) specifies the output directory of kernel builds.

Use a more generic name, 'output', to better reflect this code hunk in
the context of external module builds.
