From: Rabin Vincent on
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.
