profiles: rebase onto Gentoo's hardened profile

The default 10.0 is deprecated and removed upstream. Also, instead of
twiddling the hardened flag we should just use the hardened profile.

As part of this the host SDK no longer has multilib enabled, it isn't
actually needed for anything anyway.
profiles: disable static binaries

Left over from some odd behaviors of the ChromeOS build systems.
hard-host-depends: remove google-breakpad

This package does not build in the SDK after removing multilib support.
We don't actually need it, kill it.
