This is not quite true: programs built for Linux *do* include GNU code,
even though libc is a shared library. In particular, they include code
from libgcc.a and from crt*.o. It's just that this code is covered by
special exceptions which mean that programs which include this code
don't have to be licensed under the GPL.

No, you won't. You must abide by section 6 of the LGPL, which means
among other things that you need to provide relinkable object code,
but you don't need to provide source code.
