# Steps:
# 1) toolchain/binutils/install
#    build & install binutils
# 2) toolchain/gcc/minimal/install
#    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/headers/install
#    build & install libc headers & support files, needed for step 5
# 5) toolchain/gcc/initial/install
#    build & install an initial gcc, needed for step 6
# 6) toolchain/libc/install
#    build & install the final libc
# 7) toolchain/gcc/final/install
