Bump to the latest 4.1.7 version and improve the cross-build logic.
With the new patches the build is basically architecture-agnostic making
it possible to ditch the arch-specific cache to use a generic one.
Some toolchains might not be too happy with samba4 because of bitrot,
hopefully we'll find and fix or blacklist those with autobuilder help.
