installcheck: support it in our own testsuite

* NEWS: Update.
* tests/defs-static.in ($am_running_installcheck): New variable.
Initialize it to a default of "no", and sanity-check its value.
($am_datadir, $am_docdir, $am_automake_acdir, $am_system_acdir,
$am_bindir, $am_scriptdir, $am_pkgvdir): New variables,
initialized from AC_SUBST'ed values which are adaptively chosen
depending on whether the testsuite is running in "simple" mode
or in "installcheck" mode.
($MISSING): Remove, it's not really required by the testsuite.
($PATH): Update using `$am_bindir', not `$testbuilddir'.
* Makefile.am (installcheck-local): New target.
* lib/Automake/tests/Makefile.am (installcheck-local): New target.
(AM_TESTS_ENVIRONMENT, AM_PL_LOG_FLAGS): Adaptively choose the
`-I' flags for perl based on whether the tests are being run by
"make check" or "make installcheck".
* tests/Makefile.am (installcheck-local): New target.
(defs-static): Generate it at make time, not at configure time,
in order to correctly resolve all the indirections in the
AC_SUBST'd variables; done with the help of ...
(do_subst): ... this new macro.
(EXTRA_DIST): Explicitly distribute `defs-static.in'.
(CLEANFILES): Remove `defs-static'.
* configure.ac (AC_CONFIG_FILES): Remove `tests/defs-static'.
(AC_SUBST): Substitute also `automake_acdir', `system_acdir',
`scriptdir' and `amdir' to proper values.
* lib/Makefile.am (scriptdir):  Don't explicitly define anymore.
* lib/am/Makefile.am (amdir): Likewise.
* m4/acdir/dirlist: Remove, it's not needed anymore.  Instead
use ...
* m4/acdir/.placeholder: ... this file.
* m4/Makefile.am (EXTRA_DIST): Update.
(automake_acdir, system_acdir): Don't explicitly define anymore.
* tests/aclocal-print-acdir.test: Use new `$am_...dir' variables,
instead of hard-coding values with $testsrcdir and $testbuilddir,
to test more faithfully under "make installcheck".
* tests/amhello-binpkg.test: Likewise.
* tests/amhello-cflags.test: Likewise.
* tests/amhello-cross-compile.test: Likewise.
* tests/ansi2knr-no-more.test: Likewise.
* tests/autodist-stamp-vti.test: Likewise.
* tests/auxdir.test: Likewise.
* tests/check2.test: Likewise.
* tests/copy.test: Likewise.
* tests/multlib.test: Likewise.
* tests/obsolete.test: Likewise.
* tests/parallel-tests-interrupt.test: Likewise.
* tests/repeated-options.test: Likewise.
* tests/suffix5.test: Likewise.
* tests/tap-doc2.test: Likewise.
* tests/txinfo22.test: Likewise.
* tests/vtexi3.test: Likewise.
* tests/defs: Likewise.  Also, print the values of `$using_tap'
and `$am_running_installcheck', to simplify debugging, and do
some related code movings and tweakings.
* tests/aclocal3.test: Update to avoid possible spurious failures
when running under "make installcheck".
* tests/warnings-unknown.test: Likewise.
* tests/location.test: Likewise, and improve debugging input since
we are at it.
* tests/acloca10.test: Adapt and tweak to work also during a
"make installcheck", and not to require a pre-populated `dirlist'
file.
* tests/acloca18.test: Likewise.
* tests/dirlist2.test: Likewise.
* tests/dirlist.test: Likewise, and remove an obsolete comment.
* tests/README: Update.
* tests/dirlist-abspath.test: New test.
* tests/list-of-tests.mk: Update.
