cross/crossdirect: partially use sccache for rust (MR 4310)

Browse source 
Wrap rustc commands with sccache when building native build scripts.
More interesting will be using sscache for compiling for the target
architecture, but sccache currently refuses to cache with --sysroot.
This can be optimized further later on, get some initial support for
sccache in here first.

While at it, tweak the -vV logic to also support -V, start using semver
with this and add myself as maintainer of the package.
