Fix build on Solaris. Fixes bug #568480.

Fix linking on Solaris by checking for the nsl and socket
libraries which are needed for socket() and gethostbyname().

Don't initialize some fields of struct mh to NULL/0, they're
already set to NULL/0 by a memset(). Also this fields don't
exist on Solaris.
