Perhaps this is gcc version specific? I didn't see any other reports,

gcc is called with '-pg -mprofile-kernel', but then the record_mcount

But you see it running the script if you remove that commit? Do you
happen to see -mrecord-mcount at all in a V=1 make?
See entire make output from the two runs here:

Mystery solved! That other commit inadvertently added a trailing space
to CC_FLAGS_FTRACE, which then confused the findstring call in the
cmd_record_mcount Makefile function.
Workaround patch just posted ... kbuild experts can suggest better fixes
if that one is sub optimal.
Thanks,
