 The mcrxr instruction is being phased out. It does not exist on any of 
 our POWER 4 architecture machines. 
  
 To avoid software emulation of the instruction, please consider using 
 the CR register directly (by setting Rc=1 in the opcodes that support 
 it).

+Scanning through mini/mini-ppc.c, it seems you only need "mcrxr 0" (i.e. 
+"ppc_mcrxr (code, 0);"). If you have a spare register, an easy replacement 
+seems to be "mfxer  Rx" and "mtocrf 0, Rx" (i.e. with your current set of 
+macros: "ppc_mfspr  (code, <x>, ppc_xer);" and "ppc_mtcrf (code, 0x1, <x>);").
