Issue
what does "+" mean in makefile ?
i found "+$(call if_changed,link-vmlinux)" in kernel makefile.
it means invoke make call function. But what's the "+" usage.
Solution
The + symbol means to execute the command under make -n
See the wiki
a plus sign (+), the command is executed even if Make is invoked in a "do not execute" mode
