See 7f7f6f7ad654 ("Makefile: remove redundant tool coverage variables")
Also a 'git grep GCOV_PROFILE' shows way more places. Can't LLVM_COV
just use the already existing GCOV_PROFILE annotations or is LLVM_COV
suitable for all the files which have been excluded for GCOV?
GCOV has GCOV_PROFILE_obj.o, GCOV_PROFILE and CONFIG_GCOV_PROFILE_ALL
for a reason, no?
