3. run `make` to produce the `dbox` executable (CC,CC_FLAGS,LD_FLAGS are the env variables i use for compiler settings)
4. similar to busybox, you can either manually invoke dbox with the name of the executable (i.e. `bin/dbox ls -cCa`), or link the dbox executable to whatever you want to use (i.e. `ln bin/dbox bin/ls; bin/ls -cCa`)
5. congrats, you have built the best set of coreutils since minix
- allow a way to manually use multi-binary mode? (currently you can (in theory) just rename the `dbox` executable to whatever program you want, albiet with the slight overhead of `dbox`)
