PATCH: fix configure.ac to find functions on Solaris

[Ben Taylor]

[resent since my mail headers were missing information]

This patch allows configure.ac to generate a configure script which will
properly find some network functions that require Solaris to include -lsocket 
on. The first AC_CHECK_FUNCS tests connect, and if it's not found in 
"libc", then the existing code just adds -lsocket to the list of libraries.  
Once that  occurs,the rest of the get X by Y functions are found for a 
solaris host.

Prior to this patch, mozilla.exe would start, but would fail when looking up a 
host. When applied, this patch allows mozilla.exe to actually resolve a host 
on Solaris and render the page.
