Title:
  [SRU] Failed to create source package: Unmet build dependencies:
  bpftool:native

Status in linux package in Ubuntu:
  Fix Released
Status in linux-oem-6.17 package in Ubuntu:
  New
Status in linux source package in Noble:
  New
Status in linux-oem-6.17 source package in Noble:
  Fix Committed

Bug description:
  [ SRU Justification ]

  [ Impact ]

  Unexpected bpftool dependency.

  The build profile spec `<!stage1> <cross>` means "!stage1 OR cross",
  while it actually wants "!stage1 AND cross", which should be `<!stage1
  cross>` according to https://wiki.debian.org/BuildProfileSpec.

  This can be reproduced by attempting to create source package under FOO-amd64 
chroots:
  ```
  $ fakeroot debian/rules clean && debuild --no-lintian -us -uc -S && git clean 
-d -f -x
  ...
  dpkg-checkbuilddeps: error: Unmet build dependencies: bpftool:native
  dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
  dpkg-buildpackage: warning: (Use -d flag to override.)
  debuild: fatal error at line 1184:
  dpkg-buildpackage -us -uc -ui -S failed
  ```

  [ Test Plan ]

  ```
  $ git clone -o questing 
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/questing 
linux
  $ cd linux
  $ git checkout questing/master-next
  $ fakeroot debian/rules clean && debuild --no-lintian -us -uc -S && git clean 
-d -f -x
  ```

  [ Where problems could occur ]

  Packaging typo.

  [ Other Info ]

  Assume this affects Questing and its derived kernel linux-oem-6.17.

  ========== original bug report ==========

  $ fakeroot debian/rules clean && debuild --no-lintian -us -uc -S && git clean 
-d -f -x
  ...
  dpkg-checkbuilddeps: error: Unmet build dependencies: bpftool:native
  dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
  dpkg-buildpackage: warning: (Use -d flag to override.)
  debuild: fatal error at line 1184:
  dpkg-buildpackage -us -uc -ui -S failed

  This is a follow-up for commit "UBUNTU: [Packaging] Use host bpftool
  if doing cross-compiling" that added `bpftool:native <!stage1>
  <cross>` to Build-Depends of linux/questing, which is then copied into
  linux-oem-6.17/noble.
