Patch series "selftests: Centralize kselftest headers to avoid relative
includes".

This series centralizes the handling of kselftest.h and
kselftest_harness.h includes in selftests, replacing relative paths with a
non-relative approach using shared -I path.

Patch 1 updates the build files (Makefile and lib.mk) and include CFLAGS
in sync/Makefile to resolve not found errors.

Patch 2 applies bulk source change (patch 2 is large but it is replaced
automatically).


This patch (of 2):

Add compile flag in Makefile and export it in lib.mk.  Also add CFLAGS in
the Makefile rules to fix include path errors for kselftest.h.
