Looks great!

1) Can we remove the bash and put this directly in python (please create
bb_host_steps.py)?

2) Do you need to setup goma if we're using compile.py?

+    --build-tool "ninja" \
+    --compiler "goma" \
+    --target "$BUILDTYPE" \
+    --goma-dir "$GOMA_DIR" \
+    --build-args "All"
 }
 
 # Experimental compile step; does not turn the tree red if it fails.
