I believe what you are looking for is voidpointertype.size - it is the correct 
target-aware pointer size in the FPC compiler.                
                                                                                                    
- sizeof(pint) — reflects the host compiler's pointer size (wrong for cross-
compilation)          
- voidpointertype.size — reflects the target pointer size (set during 
psystem.pas initialisation based on the target CPU)                                                                          
                                                                                                    
Interestingly, that means dbgdwarf.pas:3317 has a bug with 
tai_const.create_8bit(sizeof(pint)) for the DWARF address_size field.                             
                                               
The code should read:                                                                   
  
  inc(G_ByteCounter, voidpointertype.size)                                                          
                                               
voidpointertype is declared in symdef.pas and is always available once the 
system unit types are initialised. You can see psystem.pas:206 uses case 
voidpointertype.size of to decide which integer types map to pointer-sized 
integers — it's the established idiom for this.

I'll test a bit later and open a MR in my initial investigation is correct.
