check_dist_tree walks -type f -o -type l, so the emitted-tree cross-check covers
regular files and symlinks under dist/. README.md said "nothing under dist/ that
the build did not write", which is broader: fifos, sockets, device nodes and
empty directories are not checked.
The exclusion stays. A build emits none of those types, none can carry a
shippable payload, and grep on a fifo would hang rather than fail. README.md,
the script's header comment and the check_dist_tree comment now say so in the
same words, so the code and the docs cannot drift apart again.
Documentation only: no non-comment line of script/verify-build changed.
