Replace hard-coded tool paths with variables, so I can override them for my system.
makefile_diff.txt
With this, I use a command like so:
make distpush CBMCONVERT="/Users/dan/Downloads/cbmconvert-main/cbmconvert" M65="/Users/dan/Google\ Drive/Retro\ Computing/MEGA65/Tools/m65.osx" M65FTP="/Users/dan/Google\ Drive/Retro\ Computing/MEGA65/Tools/mega65_ftp" USBPORT=/dev/cu.usbserial-4
