i'm going to add this flag to LKM building, as well as the kernels for
ports i can test.  it disables internal `printf' prototype mismatch,
as well as `main' warnings that -Wno-main does not get rid of.


people should start to move their kernel Makefile's and other non-hosted
parts of the tree (bootblocks come to mind) to use this flag.  it will
be necessary for post 2.95 gcc.
