Don't build it in debug mode.

 I was building it in MinSizeRel mode...
 

Also "-j 4".
Didn't want to go too much higher as this would likely bog down PC harder.
Some stuff say builds should not take quite this long, but this is what I am seeing...

 But, yeah, need to go to sleep... May poke with it tomorrow if all goes well...
 

Seems the options I had used did not enable "clang".
Had to enable clang and run again, though as LLVM itself was already built, it seemed to not need to do much with the parts already built.
So, rerun with "clang" enabled took ~ 1hr.
So, errm... Once built, how does one get it to actually get it to target the ISA.
"--target my66000-none-elf" or similar just gets it to complain about an unknown triple, not sure how to query for known targets/triples with clang.
The built "llc --version" makes no mention of MY66000...
Seems to self-identify as version 16.0.0git, host CPU znver1.
Had built the version found here:
https://github.com/bagel99/llvm-my66000
Ironically, it does seem to know about ARM64, though trying to build anything with it results in it complaining about missing headers ("bits/libc-header-start.h").
No obvious documentation besides that from LLVM itself, and not super easy to figure out otherwise. Was there some option I was supposed to give to CMake to enable the target?...
Granted, there is always a possibility that I screwed something up here (or possible interference from another LLVM version?...).
