disable fstack usage
It's only workable on gcc 4.6+... and in fact it's only
going to be interesting typically to the maintainer, so it's
commented out in Makefile.am.
Currently the worst remaining ones for x86_64 are
libwebsockets.c:2250:6:_lws_log 496 static
libwebsockets.c:2203:13:lwsl_emit_stderr 352 static
client.c:700:1:libwebsockets_generate_client_handshake 320 static
server.c:42:1:libwebsockets_decode_ssl_error 288 static
server-handshake.c:31:1:handshake_0405 272 static
client.c:368:1:lws_client_interpret_server_handshake 272 static
libwebsockets.c:447:1:libwebsockets_get_peer_addresses 256 static
daemonize.c:93:1:lws_daemonize 240 static
output.c:536:5:libwebsockets_serve_http_file 224 static
sha-1.c:131:1:sha1_step 192 static
sha-1.c:316:1:SHA1 160 static
libwebsockets.c:1604:1:libwebsocket_create_context 160 static
The top two there are error assembly buffers, they could be made
static but then they won't be usable from threaded user code.
