Subject: [PATCH] src: fix build with musl libc

The GNU version of 'struct tcphdr' is not exposed by musl libc headers
unless _GNU_SOURCE is defined. Without this definition, the build fails
with:

  rpc.c: In function 'rpc_helper_cb':
  rpc.c:351:15: error: 'struct tcphdr' has no member named 'doff'
     offset += th->doff * 4;
                 ^

Upstream status: sent
