Possibly missing `bin` directory creation on `Makefile`

[dgchrt]

First make run output:

mv: rename main.bin to bin/main.com: No such file or directory
make: *** [build] Error 1

After creating a bin directory it's clean:

Binary file start = 00000100
Records start     = 00000100
Highest address   = 0000037C
Pad Byte          = FF
Done.
