Subject: libbpf: Compile using -std=gnu89
Patch-mainline: v5.17-rc1
Git-commit: 3a74ac2d1159716f35c944639f71b33fa16084c8
References: jsc#PED-1377
The minimum supported C standard version is C89, with use of GNU
extensions, hence make sure to catch any instances that would break
the build for this mode by passing -std=gnu89.
