+# Steps:
+# 1) toolchain/binutils/install
+#    build & install binutils
+# 2) toolchain/gcc/prepare
+#    build & install a minimal gcc, needed for steps 3 & 4
+# 3) toolchain/kernel-headers/install
+#    install kernel headers, needed for step 4
+# 4) toolchain/libc/prepare
+#    build & install libc headers & support files, needed for step 5
+# 5) toolchain/gcc/compile
+#    build & install an initial gcc, needed for step 6
+# 6) toolchain/libc/compile
+#    build & install the final libc
+# 7) toolchain/gcc/install
+#    build & install the final gcc
+# 8) toolchain/libc/install
