An experiment in hybridizing overriding of autotools-conventional XYZdir vars, the goal being to be able to provide both overrriding of them at configure-time and make-time with sensible semantics. Based on notes from [forum:00d12a41f7|forum post 00d12a41f7].

+# "Re-export" the autoconf-conventional --XYZdir flags into something
+# which is more easily overridable from a make invocation.
+#
+# Based off of notes in <https://sqlite.org/forum/forumpost/00d12a41f7>.
+#
+# Consider:
+#
+# $ ./configure --prefix=/foo
+# $ make install prefix=/blah
+#
+# In that make invocation, $(libdir) would, at make-time, normally be
+# hard-coded to /foo/lib, rather than /blah/lib. That happens because
+# the autosetup exports conventional $prefix-based values for the
+# numerious autoconfig-compatible XYZdir vars at configure-time.  What
+# we would normally want, however, is that --libdir derives from the
+# make-time $(prefix).  The distinction between configure-time and
+# make-time is the significant factor there.
+#
+# This function attempts to reconcile those vars in such a way that
+# they will derive, at make-time, from $(prefix) in a conventional
+# manner unless they are explicitly overridden at configure-time, in
+# which case those overrides takes precedence.
+#
+# Each --XYZdir flag which is explicitly passed to configure is
+# exported as-is, as are those which default to some top-level system
+# directory, e.g. /etc or /var.  All which derive from either $prefix
+# or $exec_prefix are exported in the form of a Makefile var
+# reference, e.g.  libdir=${exec_prefix}/lib. Ergo, if
+# --exec-prefix=FOO is passed to configure, libdir will still derive,
+# at make-time, from whatever exec_prefix is passed to make, and will
+# use FOO if exec_prefix is not overridden.  Without this
+# post-processing, libdir would be cemented in as FOO/lib at
+# configure-time, so would be tedious to override properly via a make
+# invocation.
