Hello,

A change in last 2-3 days seems to have broken the internal library load
path or something.

Even after make bootstrap I get:

Debugger entered--Lisp error: (file-error "Cannot open load file" "subr-x")
  require(subr-x)

on starting emacs.

If I comment out the line requiring subr-x, I get another error about a
missing internal variable:

Debugger entered--Lisp error: (void-variable emacs-repository-version)
