#17 make install sysconfdir=/opt/example/etc fails

[Bishop]

making install in $topdir with $sysconfdir reset to an
installation path separate from the compiled path (for
packaging) will still cause the old (./configured)
values to be used for SOME of the make-install portion
since values such as CA_DIR are unlinked through
laundering (configure.in:237) from configured values
(such as $sysconfdir in configure.in:112) and no longer
respond to changes in the standard variables (libdir,
sysconfdir, mandir).

It simply means that packagers using redefined libdirs
or whatnot, vs DESTDIR hacks, will tear out more hair.

Simpler Workaround:
sed -i '/^config-setup:/,/^$/{/test/d}' src/Makefile
after configure finishes. Then build a new
make-install for config-setup, as required.
