When cross-compiling the second stage to a different target, we need to
make sure that the first-stage compiler can produce binaries for that
target. Using lld and llvm-objcopy as the default linker and objcopy
tool eliminates some of the dependencies on the host toolchain.

When second stage is being cross-compiled for a different platform
we need to build enough of first stage runtimes to get a working
compiler.

This is currently breaking because Linux target sysroots rely on
case sensitive filesystem which is not by default enabled on macOS.

First stage build is only a minimal build where we don't need
a complete multiarch support, but we need enough to build the
second stage.

Previously we were using default logic when building Linux runtimes
in Fuchsia toolchain, but that leads to various issues due to how
the CMake logic in compiler-rt for determining the platform support
is implemented. With this change, we will use explicit target for
every provided Linux sysroot.

We want to build the second stage compiler with libc++ and compiler-rt,
also include builtins and runtimes into extra bootstrap components to
ensure these get built.

This enables the use of install-distribution-stripped target in the
2-stage builds.

This allows passing additional CMake flags to builtins and runtimes
build through Fuchsia cache files.

Enable assertions in both stages.
Release+Asserts is fast enough.
No need to let insanity through.

It's used to determine whether terminal supports colors, but within LLVM
it's only used in handful of places and in Clang it's only used in AST
dumper, otherwise Clang relies on the -fcolor-diagnostics flag which we
pass explicitly from our build system anyway. This eliminates one of the
shared libraries dependencies making the toolchain less reliant on the
host environment.

These cache files can be used to build Fuchsia toolchain. They also
demonstrate the use of multi-target builtins build.
