Out-of-tree, doc/latexfiles points a build-tree ../psfigures at the source
copy so latex/dvips resolve ../psfigures/*.ps. The old
`test -e ../psfigures || ln -s ... ../psfigures` had two defects:
* Under a parallel docs build two .ps jobs could both see ../psfigures
absent and both run `ln -s`. The second `ln -s DIR symlink-to-dir`
nests the link *inside* the target, writing a stray
doc/psfigures/psfigures INTO THE SOURCE TREE -- an out-of-tree build
must never modify source.
* (An order-only make prerequisite is not a fix here: VPATH makes make
"find" ../psfigures in the source tree and skip creating the build link
latex actually needs.)
Use a shell test (VPATH-immune) that is both idempotent and race/nest safe:
`test -d ../psfigures || ln -sfn ${MAGICSRC}/doc/psfigures ../psfigures`.
`test -d` is true in-tree (real source dir) and once the build symlink
exists; `ln -sfn` (force + no-dereference) replaces an existing symlink in
place instead of nesting inside it.
Verified in/out of tree under -j12: 28/28 docs, correct single-level build
symlink, source tree never touched (in-tree psfigures stays a real dir).

Switch the 5 nested children (scmos/cif_template, doc/man, doc/tutcells,
doc/html, doc/latexfiles) to configure-provided substitution:
srcdir = @srcdir@
VPATH = @srcdir@
MAGICDIR = @top_builddir@ (resolves to ../.. for these nested dirs)
Verified out-of-tree: full `make` rc=0; cif_template gets
srcdir=<src>/scmos/cif_template, doc/latexfiles MAGICDIR=../..; scmos
techs + 27/28 docs build.
With this, every module except readline/ is a configure-generated
Makefile.in using @srcdir@ substitution.

Convert the last nested children to Makefile.in and switch their parents
from the -f fallback to native recursion (they now have generated build
Makefiles). Rename and rewire are one unit: a pure rename would break the
parent's -f path to the (now-.in) child.
Converted (5): scmos/cif_template, doc/man, doc/tutcells, doc/html,
doc/latexfiles. Pure renames -- still build via the srcdir derivation;
@srcdir@ substitution follows.
Rewired to native `make -C <child>` (config.status now creates the child
build dirs + Makefiles):
* scmos/Makefile.in: cif_template build + clean.
* doc/Makefile.in: install/install-tcl over man/tutcells/html/latexfiles.
* Makefile.in: the docs: target -> `make -k -C doc/latexfiles all`.
The `mkdir -p` and `-f ${MAGICSRC}/.../Makefile` are dropped in each.
* configure.in: AC_CONFIG_FILES for the 5 children; regenerated configure.
* .gitignore: ignore each generated child Makefile, same commit.
Verified out-of-tree: full `make && make install` rc=0, 376 files --
scmos recurses natively into cif_template (8 objs), docs regenerate via
native doc/latexfiles (27/28), man pages install via native doc/man.
