# 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
