it is recursive by nature:
In Makefile.build u see the following:
PHONY += $(subdir-ym)
$(subdir-ym):
$(Q)$(MAKE) $(build)=$@
And build is defined in scripts/Kbuild.include:
###
# Shorthand for $(Q)$(MAKE) -f scripts/Makefile.build obj=
# Usage:
# $(Q)$(MAKE) $(build)=dir
build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
and shown in the remarks statement above, the "build" variable is used
to construct the whole string: "$(Q)$(MAKE) $(build)=dir".
