To clarify the article's text, uClinux is not (just) a distribution, but a version of the kernel that rus on MMU-less hardware.
The full Linux kernel does have m68k support, but it needs a 68020 or better CPU. This gets you real memory protection, VM etc.
Wasn't uClinux merged into mainline a long time ago?
You can build it from the mainline git repo, but what you get is a version of the kernel with defining features of Linux/Unix missing.
What's missing? I haven't used uClinux before but I consider it on a cortex m4 - what should I be wary of?
Well...68020+68851 PMMU chip. Regular Linux won't run on just an '020.
