Congratulations for this brave endeavor!  :-)

I tried to build it on NixOS GNU/Linux on x86_64 and noticed several
glitches related to the test suite:

  1. The tests do “. common”, which means that ‘common’ is looked up in
     $PATH, which fails unless ‘.’ is in $PATH.

  2. Why is a custom ‘check-TESTS’ target needed in the ‘v’ (!)
     directory?

  3. Why move executables from ‘src’ to ‘src/0pre/bin’?

  4. How about using ‘set -e’ in test scripts?

  5. The ‘rlog’ program as run by the tests segfaults:

Well, I hope this helps.  :-)
