Alexei Starovoitov 2532f849b5 bpf: Disallow BPF_PRELOAD in allmodconfig builds ... The CC_CAN_LINK checks that the host compiler can link, but bpf_preload relies on libbpf which in turn needs libelf to be present during linking. allmodconfig runs in odd setups with cross compilers and missing host libraries like libelf. Instead of extending kconfig with every possible library that bpf_preload might need disallow building BPF_PRELOAD in such build-only configurations.
