Move SYSVONLY define from version.h to the individual makefiles for Linux

Add makefile for Linux on x86_64 platforms
Remove include <stropts.h> for Linux as modern systems have dropped this
Adjust code to account for fcntl() vs ioctl() for generating signals on X I/O
Adjust includes for time related include files for modern Linux systems
