We may do both.  Such files that will compile the same (i. e. where no
specific code changes are done depending on CONFIG_PRELOADER or other
settings) should re-use the existing object files. Allothers need to
be rebuild, obviously.

But this is optimization already, which should be done in a second
stage. I will not complain when we start with rebuilding all needed
objects.

Best regards,

Wolfgang Denk
