Then you are still trusting the compiler, and the compiler which
compiled the compiler. I suggest you read Ken Thompson's Turing
Award lecture "Reflections on Trusting Trust".

You might think that you can avoid Thompson's hack by disassembling
the object code, but even then you're trusting a possibly compromised
disassembler or link loader.
"Trust" is a deeper can of worms than is solvable by a simple
re-compilation.

BTW, from a practical point of view, there's more avenues for evil
in libc than in the kernel. So don't forget to read that too.
