On ARM, we have two ABIs, and the ABI used is controlled via a config option. Object files built with one ABI can't be merged with object files built with the other ABI. So, record_mcount.pl needs to use the same compiler flags as the kernel when generating the object file with the mcount locations. Ensure this by passing CFLAGS to the script.

Again, I'll have to test this on other archs, just to make sure its does not cause any side effects. Oh, I forgot I now have a MIPS board I can test on too. I'll probably do this on Monday. Thanks, -- Steve
