makefile: use conditional assignment for KBUILD_OUTPUT
Refer [1],from make 4.4, all variables that are marked as export will
also be passed to the shell started by the shell function. use "=" will
make KBUILD_OUTPUT always empty for shell function, use "?=" to make
"export KBUILD_OUTPUT" in enrironment can work.
[snip of 4.4 NEWS]
* WARNING: Backward-incompatibility!
Previously makefile variables marked as export were not exported to
commands
started by the $(shell ...) function. Now, all exported variables are
exported to $(shell ...).
