[CFT] WITH_META_MODE: Working incremental build [only on i386 and amd64] [filemon fails to load on powerpc64]

[Mark Millard]

May be Nathan Whitehorn knows what is going on that prevents filemon.ko from loading for powerpc64 based on how it is now built (added for more than i386 and amd64 as of -r301130)?

Nathan: See below if it sounds like something you might have a clue about. As to why this comers up: Loading filemon.ko is required in order for WITH_META_MODE=yes to work for incremental builds.
