[PATCH 3/3] selftest/powerpc: make sub-folders buildable on it own

Madhavan Srinivasan maddy at linux.ibm.com
Thu Feb 29 20:37:11 AEDT 2024 

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
