Makefile

# Simple makefile wrapper, see "make help". Mostly calls various build scripts:

# scripts/make.sh - compile toybox
# scripts/install.sh - install toybox
# scripts/genconfig.sh - create/modify .config file
# scripts/test.sh - run tests against command(s)
# scripts/single.sh - build standalone command(s)
# scripts/change.sh - build all commands standalone
# mkroot/mkroot.sh - build self-contained test system bootable under qemu
