illumos gate

It seems likely we need an exception for the stack protector in the S10 brand shared object. If we have a fix for this, is that something you can help test somehow?

I have set up a new build system, and currently building the gate with the following fix:

The build of the gate has been finished, the 32/64 bit s10_brand.so.1 libraries have been copied over to my production system and I'm able to use zlogin again, therefore this bug is fixed.
