Bug Description
SRU justification:
[Impact]
This is encountered on linux kernel derivatives with fewer configuration options enabled.
First time saw on jammy:linux-
During build, it fails with the following error:
...

ERROR: modpost: "cfg80211_

because CONFIG_USB=n, CONFIG_CFG80211=n
[Fix]
Add a rule to build oss4 when CONFIG_USB=y/m and CONFIG_
BUILD_EXCLUSIVE
[Test Plan]
1.For lunar and mantic:
Install a new version of linux-kvm
apt install oss4 will fail as described above.
After the fix, it will not be built at all.
2. In #2011551 the bug was solved for jammy, but BUILD_EXCLUISVE
For jammy it should not be built with both previous version and this version. Try with linux-kvm as well.
Once packages are in proposed, a new adt is triggered against proposed for mantic/
[Where problems could occur]
Low possibility of new issues.
[Note]
This fix is not scalable in the sense that if configuration name changes, the module has to be changed as well.

Mantic, lunar and jammy fixes are attached.
Tested locally on kvm instances when possible (for jammy and lunar only) because kvm does not have these config options enabled.
