rules.mak has no @...@ substitutions, so there is no reason to copy it into
the build top. Point all 38 subdir Makefile.in includes at the source copy
directly -- ${MAGICSRC}/rules.mak instead of ${MAGICDIR}/rules.mak -- and
remove AC_CONFIG_FILES([rules.mak:rules.mak]) from configure. defs.mak (the
one make fragment with substitutions) remains the only generated file in the
build top. readline/ and the top Makefile never included rules.mak, so they
are unaffected; AC_CONFIG_SRCDIR(rules.mak) (the srcdir sentinel) is kept.
Now editing rules.mak in the source tree takes effect without reconfiguring.
Verified rc=0, 375 files, both in-tree and out-of-tree; out-of-tree build
top has no rules.mak; distclean rc=0.

Switch the 13 near-standard/outlier modules to configure-provided
substitution (same template as the standard modules):
srcdir = @srcdir@
VPATH = @srcdir@
MAGICDIR = @top_builddir@
Their sibling-object refs (${MAGICDIR}/<mod>/lib*.o) and custom rules are
unchanged: ${MAGICDIR} = @top_builddir@ (the build top) so the sibling
objects resolve into the build tree, and $(srcdir) now comes from
@srcdir@ instead of the derivation.
Verified out-of-tree: `make modules libs` builds all 33 module libraries;
the five Tcl auto-load libraries (magiclef.so, tclplot.so, tclroute.so,
exttospice.so, exttosim.so) link (sibling refs resolve to the build top).

Third batch of the Makefile.in migration: near-standard modules
(utils windows commands database) and the program/.so outliers
(lef plot router ext2spice ext2sim extcheck net2ir graphics oa).
Pure renames -- content unchanged, so each still builds via the defs.mak
srcdir derivation; the @srcdir@ substitution follows.
* git mv <dir>/Makefile -> <dir>/Makefile.in (13 modules)
* configure.in: AC_CONFIG_FILES for each; regenerated configure.
* .gitignore: ignore each generated <dir>/Makefile, same commit.
These modules carry sibling-object refs (${MAGICDIR}/<mod>/lib*.o) and
custom rules; those keep working unchanged (${MAGICDIR} = the build top,
$(srcdir) from the derivation). readline/ remains on the -f path.
Verified out-of-tree: config.status writes 35 module Makefiles (22 + 13);
`make modules libs` builds all 33 module libraries (rc=0).
