errcodes.h and others not generated when compiling 13.6 on M1 Mac

Hello

I recently upgraded one of our applications to use postgres 13.6. When I try to compile from a source checkout or by running asdf install (our version manager which also compiles 13.6) I get the same error message:

../../src/include/utils/elog.h:71:10: fatal error: 'utils/errcodes.h' file not found

After digging around in the source it looks like it's supposed to be generated. I can't figure out why this isn't working on my machine though. It seems to happen on any M1 mac (my colleagues can reproduce it)
