RFR: 8244224: Implementation of JEP 381: Remove the Solaris and SPARC Ports (build system)

[Erik Joelsson]

The build changes look ok and will remove all support for building on or 
recognizing either Solaris or Sparc.

Kim's note is valid and I would recommend removing that variable completely.

I do think it would be possible to leave enough in there to enable zero 
builds on Linux Sparc, but I assume you would need help from someone 
developing the necessary patch as we don't have access to a Linux Sparc 
build environment to test it out.

The other patches are being sent out for review to mailing lists appropriate for the respective areas the touch. An email will be sent to jdk-dev summarizing all the patches/reviews. To be clear: this patch is *not* in itself complete and stand-alone - all of the (six) patches are needed to form a complete patch. Some changes in this patch may look wrong or incomplete unless also looking at the corresponding changes in other areas.
