When invoked from a context like this... my-infix-spin$ make O=x-my-build x86_64_defconfig ...where the spin's Makefile would trigger the generation of the defconfig based on some fragments, the value of O passed via the environment would be ignored since the spin's Makefile typically overrides it. Therefore, pass it as a make variable instead, which takes precedence.
