[PATCH 1/2] ftrace: pass KBUILD_CFLAGS along with CC to record_mcount.pl

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.
