- # Steps to build toolchains
- # 1) build and install binutils
- # 2) build and install mpfr, mpc, libelf and gmp
- # 3) build and install minimal gcc c compiler
- # 4) install kernel-headers
- # 5) install libc headers
- # 6) build and install initial static gcc
- # 7) build and install full libc
- # 8) build and install full shared gcc
- # 9) rebuild and install full libc (in case of musl/uclibc)
- # 10) build and install gdb debugger
