So I notice this successful build also is also printing the recursive
make invocation (and it seems to be running in parallel) whereas the
failing build just goes straight to printing the GEN lines.  I think
this all this points to some change in the build system on the server;
was 'make' updated recently?

make -C lib all
make info-real info-dir
make[1]: Entering directory '/build/emacs-git/src/emacs-git/lib'
make[1]: Entering directory '/build/emacs-git/src/emacs-git'
make -C doc/lispref info
  GEN      alloca.h
  GEN      dirent.h
