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
