tests: use append mode to capture parallel make output
This will allow us to run the Automake testsuite forcing all the make
invocations in the test cases to run in parallel mode [1], but without
hitting the spurious failure reported in automake bug#11413.
See also:
<http://lists.gnu.org/archive/html/bug-make/2013-05/msg00135.html>
The make invocations in the test cases can be forced to run in parallel
mode by, e.g., invoking "make check" like this:
make check AM_TESTSUITE_MAKE="make -j16"
The possible spurious failures hinted above are due to the fact that
the redirected output of parallel make can racily lose lines. For
example, if GNU make (3.82) is run with -j10 on a Makefile like this:
all = 0 1 2 3 4 5 6 7 8 9
default: $(all)
$(all):
@sleep 0.$$(($RANDOM % 10)); echo $@
and has its standard output redirected in overwrite-mode to a regular
file, it looses a line of that output every 15 runs or so on a Fedora
17 system with 64 ppc64 cores. Redirection in append mode does not
suffer of this problem, as explained here:
<http://lists.gnu.org/archive/html/automake-patches/2009-03/msg00073.html>
See also previous commits v1.12-63-g45c1fcd of 2012-05-05 (tests: use
append mode to capture parallel make output) and Release-1-10-280-g6426999
of 2009-03-10 (Use append mode to capture parallel test output).
* t/ax/am-test-lib.sh (run_make): Adjust and enhance.
* t/lisp8.sh: Take advantage of the enhancement, nd stop doing output
redirection for $MAKE by hand.
* t/tap-more.sh: Likewise.
* t/parallel-tests-concurrency.sh: Likewise.

tests: avoid '$MAKE' redirections, use 'run_make' instead
The use 'run_make' with the -E, -O and -M option, it is more
idiomatic now. Also, this way, centralized fixes and improvements
done in 'run_make' will automatically propagate through most of
the testsuite.
* syntax-checks.mk (sc_tests_no_run_make_redirect): Also check against
'$MAKE' invocations that uses output redirections (and not only against
'run_make' invocation that do so).
* Several tests: Adjust (and few minor cosmetic changes as well, while
at it).

tests: remove exec bit from all of them ('micro' branch)
It gives the impression that they are directly runnable, as with
"./t/foo.sh", but it has been a while since that was the case. Today,
tests are runnable only through "make check" or "./runtest".
This change is for the 'micro' branch (automake 1.13.2a). It will
soon be followed by similar patches for the 'maint' branch (automake
1.13a) and the 'master' branch (automake 1.99a).
* t/*.sh, t/*.tap: Remove executable bit.
* maint.mk (sc_tests_executable): Remove.
(syntax_check_rules): Adjust.
* gen-testsuite-part: Set permissions of generated tests to
'444' (-r--r--r--), rather than 555 (-r-xr-xr-x).

tests: prefer including 'test-init.sh' rather than './defs'
This is a follow-up to today's commit v1.12.4-22-g0610fc8,
"tests: prepare to move ./defs to t/ax/test-init.sh"
* All tests: To run the common setup, use the command:
. test-init.sh
instead of the older, "historical" one:
. ./defs || exit 1
Note that the "|| exit 1" wasn't really useful, since the 'errexit'
shell flag is in effect in both './defs' and 'test-init.sh', and all
the known shells that are good enough to run the automake testsuite
do automatically exit with error when a sourced file cannot be found
(at least, they do so in non-interactive mode, which is the only
mode that concerns us in the testsuite).
* t/ax/tap-summary-aux.sh, t/ax/testsuite-summary-checks.sh: Likewise.
* gen-testsuite-part: Do the same in the generated tests.
