Gbp-Dch: Ignore

Closes: #869668

In kernel 4.8 the vsyscall emulation framework was removed, and the new
interface is only supported in dietlibc 0.33 or higher. To make sure
the code is never built against older versions, bump the Build-Depends.

Closes: #845937

Intel microcode has special alignment requirements that cannot be
fulfilled with the current cpio logic. Instead of trying to do this
manually, rely on iucode_tool to generate an early-initramfs CPIO
image. For a detailed explanation, please read Debian bug #840255.

An arbitrary number of early-initramfs CPIO images can be prepended to
the initramfs itself, so this logic won't interfere with other
early-initramfs image logic.

Closes: #840255

dietlibc is now available on all release architectures and most ports.
There is currently no architecture where dietlibc is not available but
musl isn't.

It conflicts with the default initramfs-tools (Priority: optional) and
should hence be Priority: extra as per policy, section 2.5.
