Patch - check for msghdr.msg_control on Sparc-Solaris

[Warren_Baird at cimmetry.com]

ChangeLog:

    - added a test for the msg_control field in struct msghdr
      (does't appear in sparc-solaris)


Wordier Description:

This is the first part of a series of five patches needed to get wine
compiled on sparc-solaris, and some of the provided applications to
compile and run.

I've verified that wine compiles with all five patches applied under
linux-x86 and that the basics still work...
