Unset versioned gcc-12 for hwe-5.19 build

[Kleber Sacilotto de Souza]

[ Impact ]
In order to use the same compiler as used for kinetic:linux (gcc-12) we have made some changes to explicitly compile jammy:linux-hwe-5.19 with the same compiler. These changes were mainly part of bug 1999750 and bug 1991664. However, such changes are breaking the build of a number of dkms packages.

[ Fix ]
The proposed temporary workaround is to revert commit "UBUNTU: [Packaging] use versioned gcc-12", which would make the kernel compile with the default GCC in Jammy (gcc-11), while a proper solution is being worked on.

[ Where problems could occur ]
gcc-12 is necessary to enable some of the new security-related kernel configs, so going back to gcc-11 will disable such features. However, this would not regress users when upgrading from the generic kernel to hwe-5.19 in Jammy.

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

This bug is awaiting verification that the linux-hwe-5.19/5.19.0-30.31~22.04.1 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!
