Subject: Capitulate on SCTP vs sparc-sun-solaris2.10
Despite the efforts of commits 1df74351 and 111261d1 to salvage it, SCTP
is just flakey on sparc-sun-solaris2.10. In addition to the woes of the
loopback address, even connect on other addresses sporadically returns
{error, eafnosupport}, so the initial check for a working SCTP (aka
resistance) is futile. Revert both commits.
