Build breaks when executing make with run_tests for sub-folders
under powerpc. This is because, CFLAGS and GIT_VERSION macros are
defined in Makefile of toplevel powerpc folder.
make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm'
gcc hugetlb_vs_thp_test.c ../harness.c ../utils.c -o /home/maddy/selftest_output//hugetlb_vs_thp_test
hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory
6 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
Fix this by adding the flags.mk in each sub-folder Makefile. Also remove
the CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile since
the same is definied in flags.mk
