9 # Steps:
10 # 1) toolchain/binutils/install
11 # build & install binutils
12 # 2) toolchain/gcc/minimal/install
13 # build & install a minimal gcc, needed for steps 3 & 4
14 # 3) toolchain/kernel-headers/install
15 # install kernel headers, needed for step 4
16 # 4) toolchain/libc/headers/install
17 # build & install libc headers & support files, needed for step 5
18 # 5) toolchain/gcc/initial/install
19 # build & install an initial gcc, needed for step 6
20 # 6) toolchain/libc/install
21 # build & install the final libc
22 # 7) toolchain/gcc/final/install
23 # build & install the final gcc
24 # 8) toolchain/libc/utils/install
25 # build & install libc utilities
26 #
27 # For musl, steps 2 and 4 are skipped, and step 3 is done after 5
