Add support for the rumprun unikernel
For most parts, rumprun currently looks like NetBSD, as they share the same libc and drivers. However, being a unikernel, rumprun does not support process management, signals or virtual memory, so related functions might fail at runtime. Stack guards are disabled exactly for this reason. Code for rumprun is always cross-compiled, it uses always static linking and needs a custom linker.
