Not an issue but perhaps worth noting the following issues and adding to the documentation?

1. Homebrew on macOS now installs into /opt/homebrew/ so you need to adjust paths inn the Makefile appropriately.
2. If you have installed binutils with Homebrew, this will not build on M1 without deactivating them.

So need to (1) edit the Makefile:85 to

 ifdef OSX
    INCLUDE_PATHS += -I/opt/homebrew/include/libusb-1.0
    LDLIBS = -L. -L/opt/homebrew/lib -lusb-1.0 -ldl -lncurses -lpthread -lintl -L$(OLOC) -l$(ORBLIB)

and (2) need to (at least temporarily) move aside any binutils installed in /opt/homebrew/opt/binutils
mv /opt/homebrew/opt/binutils ~/binutils
