kbuild: deb-pkg: add comment about future removal of KDEB_COMPRESS
'man dpkg-deb' describes as follows:
DPKG_DEB_COMPRESSOR_TYPE
Sets the compressor type to use (since dpkg 1.21.10).
The -Z option overrides this value.
When commit 1a7f0a34ea7d ("builddeb: allow selection of .deb compressor")
was applied, dpkg-deb did not support this environment variable.
Later, dpkg commit c10aeffc6d71 ("dpkg-deb: Add support for
DPKG_DEB_COMPRESSOR_TYPE/LEVEL") introduced support for
DPKG_DEB_COMPRESSOR_TYPE, which provides the same functionality as
KDEB_COMPRESS.
KDEB_COMPRESS is still useful for users of older dpkg versions, but I
would like to remove this redundant functionality in the future.
This commit adds comments to notify users of the planned removal and to
encourage migration to DPKG_DEB_COMPRESSOR_TYPE where possible.
