+# Configure flag notes:
+#  1. Standard flags. See gcc.morph.
+#  2. See stage1-gcc.morph.
+#  3. 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.
+#  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.
