system: Extract target-specific globals to their own compilation unit

Browse source 
We shouldn't use target specific globals for machine properties.
These ones could be desugarized, as explained in [*]. While
certainly doable, not trivial nor my priority for now. Just move
them to a different file to clarify they are *globals*, like the
generic globals residing in system/globals.c.

Since arch_init.c was introduced using the MIT license (see commit
ad96090a01), retain the same license for the new globals-target.c
file.
