In order to prevent such build failures to happen, we simply prevent libtirpc from being selected when such toolchains are used. This is not a big problem, since they provide native RPC support. Also, since they provide native RPC, we don't have to propagate this new dependency to the reverse dependencies of libtirpc, because they all use native RPC when available. The exception to this rule is the rpcbind package, which can only use the libtirpc implementation of RPCs, and not the native one of C libraries. Therefore, the dependency is propagated to the rpcbind package.
