+    #  2. Our binutils is for the final $TARGET, rather than the intermediate
+    #     target our GCC is being built for, so we need to set
+    #     with-build-time-tools to get it to find our binutils at
+    #     build-time and with-as and with-ld so our temporary GCC uses
+    #     the appropriate tools when it compiles our libc, rather than
+    #     trying to use $TARGET_STAGE1-as when producing binaries.
+    #  3. Look for headers in $sysroot/$PREFIX/include when compiling.
+    #     It's neater to do this than have to specify the full header path.
+    #     FIXME: Probably not needed here since we configure without headers,
+    #            remove and try a rebuild.
+    #  4. 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.
