+  #     /tools/include is in the include path for the newly built GCC. We
+  #     set it by default to a non-existent directory to avoid GCC looking
+  #     at the host dirs, in case we forget to give it at runtime.
+  #  3. Disable searching /usr/local/include for headers
+  #  4. The pass 1 compiler needs to find the libraries we build in pass
+  #     2.  Include path must be set explicility, because it defaults to
+  #     $SYSROOT/usr/include rather than $SYSROOT/include.
+  #  5. Disable stuff that doesn't work when building a cross compiler
+  #     without an existing libc, and generally try to keep this build as
+  #     simple as possible.
