I fix above code for production use:
B := $(abspath .)/
ifeq '' '$(filter %/,${B})'
$(error B value must end with slash but actually is '${B}')
endif
ifeq '' '$(wildcard ${B})'
$(shell mkdir -p ${B})
endif
It handle case when user set B without trailing slash and dynamically create
non-existing dir.
