cpr0.o is not generated by the compiler from Pascal code, but directly  
from assembler. The code in that file is not specific to any ABI. The  
Makefile does not appear to pass the proper parameters to the  
assembler when processing that file during a compilation for the ARMHF  
target, so it doesn't get the proper markers. I'm not even certain  
whether the Makefile can easily determine that we are compiling for  
ARMHF.
