[Xymon] 4.3.16 make depends on gnu find/xargs

I'm not doing much Solaris any more, but it makes life a lot easier if you install all the gnu packages (gcc, binutils, coreutils, etc) and make sure that your systems all hit them first. You can also find them in /opt/sfw but that's usually a much older version.

Open source SW is overwhelmingly developed under linux these days, so unless you've got a strong reason for keeping the Sun/Oracle stuff first (like, running a lot of in-house code that requires Sun/Oracle compilers, or systems that are super locked down), going GNU-ish will just make your life much saner.
