Remove obsolete build flags in derivative kernels

[Juerg Haefliger]

[Impact]

Note: This impacts derivative kernel packages only.

Old and obsolete build flags in derivative kernel packages might result in unexpected packaging behavior, like broken builds, building of unwanted packages, ...

[Fix]

Remove old and obsolete build flags:
do_enforce_all
do_tools_host
do_tools_common
do_libc_dev_package
do_doc_package

[Test Case]

Build packages and verify that the resulting set of binary packages is as expected.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1005.5 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
