It seems Giacomo Olgeni's patch that this patch depends on
is missing. erts/configure will not define 
HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_SACKDELAY so it will
be disabled on all platforms even the ones that have
that flag... And that would be bad.

sorry about me not managing to rework that issue,
other emergencies came in the way...
