Alexander Thomas 5f8c21f9e9 [build] Use a sysroot also for the host toolchain when cross compiling 
Previously, we didn't use a sysroot for the host toolchain used to
create the host_tool used in dart_actions. The compile action then
failed on the new goma backend causing long build times.

Before (dart-sdk-linux-try/429, ~38 mins):
finished=10627 cache_hit=7334 retry=3277 fail=3277

After (dart-sdk-linux-try/430, ~12 mins):
finished=10625 cache_hit=7352 retry=0 fail=0

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
