In driver/Makefile, the rule which remakes ivtv-svnversion.h fires every
time, which causes 8 other files to trigger.
Following by hand, I don't understand the first "if" clause and why it
isn't matched, however...
I created the attached patch to limit the unneccesary rebuilds. It
creates a temporary ivtv-svnversion.h and only changes the original if
they differ.
Cheers,
Phil
