* examples/c/calc/calc.y: Restore to its original state, with
parse.error=detailed instead of parse.error=custom (this example
should be simple).
* examples/c/calc/calc.test: Check syntax errors.
* examples/c/lexcalc/parse.y: Add comments.

* examples/c/reccalc/local.mk: Complete dependencies, including for
earlier versions of Automake (for sake of our CI, on top of Ubuntu
Xenial/Bionic, which feature only Automake 1.15).
(%D%/scan.c %D%/scan.h): Upgrade to the full version provided in
Automake's documentation.
It works only in implicit rules (or with GNU Make, but not with
Solaris Make).

Diagnosed thanks to Kiyoshi Kanazawa.
* examples/c/reccalc/local.mk, examples/d/local.mk,
* examples/java/local.mk: Don't use $< in non implicit rules.
Because some of our examples use
%C%_reccalc_SOURCES = %D%/parse.y
Automake ships parse.y and parse.c, and possibly parse.h when it
"understands" that there is one. This is not what we want: ship only
parser.y. Yet we still want to use Automake to compile the sources
from parser.y. The easiest seems to use
nodist_%C%_reccalc_SOURCES = %D%/parse.y
together with
dist_reccalc_DATA = %D%/parse.y %D%/scan.l %D%/Makefile %D%/README.md
which guarantees that parse.y is indeed shipped.
* examples/c/calc/local.mk, examples/c/lexcalc/local.mk,
* examples/c/reccalc/local.mk: Always use nodist_*SOURCES for parsers,
let the dist_*_DATA rules do their job.
* cfg.mk: Disable checks where needed (e.g., we do want to check the
behavior with tabs).
(sc_at_parser_check): Remove. Unfortunately since
a11c144609 we no longer use the './'
prefix to run programs in the current directory. That was so that we
could run Java programs like the other, although they are no run with
the `./` prefix (see 967a59d2c0).
As a consequence this sc check no longer makes sense.
However, since now AT_PARSER_CHECK passes the `./` prefix itself, this
sc-check was superfluous.
* examples/c/reccalc/scan.l: Use memcpy, not strncpy.
* src/ielr.c, src/reader.c: Obfuscate "lr(0)" so that the sc-check for
"space before paren" does not fire.
* tests/diagnostics.at: Avoid space-tab, use tab-tab.
