Extend the out-of-tree build to the outliers deferred earlier, and
audit install sourcing. All are read-source / write-build now.
Tcl auto-load shared libraries (built via each module's `tcl-main`;
not part of the default TCL build, but now correct when invoked):
* lef/plot/router/ext2spice/ext2sim: the hand-written object rules
(tcllef.o, tclplot.o, tclroute.o, spicewrap.o, spicehier.o, simwrap.o,
ext2sim_main.o) compiled a bare-name source from the cwd; switch to
`-c $< -o $@` so the source is found via VPATH and the object lands in
the build tree. ext2sim_main.o also swaps the hard-coded -I${MAGICDIR}
for ${CPPFLAGS} (build + source include paths). ext2spice spice2sim
install copies $< (source script). Sibling ${MAGICDIR}/<mod>/lib*.o
refs already resolve into the build tree (MAGICDIR = build top).
oa (disabled by default; OpenAccess):
* CXX_INCLUDES -I. -> -I$(srcdir) -I${MAGICDIR} -I${MAGICSRC} so the C++
sources, generated database/database.h, and cross-module headers all
resolve out-of-tree; .deps and objects were already build-local.
doc/latexfiles PostScript regeneration:
* Split PS_SRCDIR (pre-built PS shipped in the source tree, read-only)
from PS_GENDIR (= psfiles in the build tree). `all` / the .tex.ps
rule now regenerate into PS_GENDIR (mkdir -p; latex reads $(srcdir)
via TEXINPUTS; dvips writes the build tree) instead of writing back
into the source psfiles dir. install takes each .ps from PS_GENDIR if
regenerated there, else the pre-built PS_SRCDIR copy.
Verified out-of-tree (make modules; then per-module tcl-main):
* magiclef.so / tclplot.so / tclroute.so / exttospice.so / exttosim.so
all build into the build tree (rc=0); oa.o builds into the build tree;
source tree stays clean.
* install-tcl copies each .so from the build tree.
* Install-location audit on a full `make install DESTDIR=...`: generated
data (scmos.tech, .magicrc, magic.tcl, tclmagic.so) matches the build
tree; verbatim data (glyphs, fonts, magicps.pro, man pages, doc PS)
matches the source tree.
* DESTDIR: two distinct prefixes install 376 files each, independent and
fully contained (nothing written outside DESTDIR).

Also fixed up CC/CXX/CXXFLAGS in the same way.
Main notable concern the tclmagic.so now has reordered position of
$LDFLAGS (was start AND end of list, now start of list only),
$LDDL_FLAGS would have already provided it start of list, so it
would be duplicated set of options.
@LDDL_FLAGS@ no longer prepend $LDFLAGS which is now explicit in the
Makefile to allow specific target control.
The purpose of all this is the toplevel ./configure now has LDFLAGS
control passed down to linker command lines as configure --help
indicates.
