Someday Microsoft comes up with Windows for SPARC that uses same system calls, i.e. H/W is abstracted. Any Win32 program would run on that too.

Virtual Machines (such as JVM) do exactly that. They provide a consistent set of instructions to the programs accross platforms. Underneath these instructions are executed differently on different systems.

Even a JVM running in a embedded system will still run on an embedded OS, however minimalist that is.
