From: "Luis R. Rodriguez" <mcgrof@xxxxxxxxxx>
scripts/module-common.lds is currently pretty static, in the
future this may change and we will want access to kernel macros
to help expands certain areas. To get access to use macros we
need to generate module-common.lds from module-common.lds.S, for
now though only enable the generation. We'll later expand on this
as needed.
Since this file is now generated add it to .gitignore.
v4: add file to MAINTAINERS
v3: new to this series
