Since Buildroot commit3145adfb69("package/libbpf: needs headers >= 4.13"), libbpf depends on Linux headers >= 4.13. This requirement renders the explicit list of supported architectures, previously added inf693354c30overly restrictive, as the syscall number for bpf(2) has been defined since Linux 3.18. Commitf693354c30("package/libbpf: add BR2_PACKAGE_LIBBPF_ARCH_SUPPORTS") was introduced to fix a build issue where a toolchain using very old kernel headers (3.13) failed to build libbpf for ARM, but these architecture dependencies are no longer needed due to the bump on the kernel headers version requirement.
