   4 # Steps to build toolchains
   5 # 1) build and install binutils
   6 # 2) build and install mpfr, mpc and gmp
   7 # 3) build and install gcc c compiler
   8 # 4) install kernel-headers
   9 # 5) install libc headers
  10 # 6) build and install full gcc
  11 # 7) build and install full libc
  12 # 8) build and install gdb debugger
