Or any of the Makefile.in files have changed. Or any of the command line options have changed. Or various environment variables have changed. Or a target file has been altered outside kbuild control. Or the compiler has changed. Or ... the list goes on.
Coding a special case to work out if the existing global makefile can be reused is horribly error prone. And it would take just as long as rebuilding the global makefile from scratch.
