 # Main makefile for the toolchain
 #
+# Steps:
+# 1) toolchain/binutils/compile
+#    build & install binutils
+# 2) toolchain/gcc/minimal/compile
+#    build & install a minimal gcc, needed for steps 3 & 4
+# 3) toolchain/kernel-headers/compile
+#    install kernel headers, needed for step 4
+# 4) toolchain/libc/headers/compile
+#    build & install libc headers & support files, needed for step 5
+# 5) toolchain/gcc/initial/compile
+#    build & install an initial gcc, needed for step 6
+# 6) toolchain/libc/compile
+#    build & install the final libc
+# 7) toolchain/gcc/final/compile
+#    build & install the final gcc
+# 8) toolchain/libc/utils/compile
+#    build & install libc utilities
+#
+# For musl, steps 2 and 4 are skipped, and step 3 is done after 5
