  maintcheck: reduce code duplication, increase coverage
  
  * syntax-checks.mk: Move ...
  (sc_tests_plain_aclocal,
  sc_tests_plain_autoconf,
  sc_tests_plain_perl,
  sc_tests_plain_autoupdate,
  sc_tests_plain_automake,
  sc_tests_plain_make,
  sc_tests_plain_autoheader,
  sc_tests_plain_autoreconf,
  sc_tests_plain_autom4te): ... all these targets ...
  (sc_tests_plain_egrep_fgrep): ... and part of this target ...
  (sc_tests_plain_check_rules): ... into this variable, and
  reimplement their recipes ...
  ($(sc_tests_plain_check_rules)): ... with this static pattern
  rule.  Enhance the coverage they offer a little since we are
  at it.
  (sc_m4_am_plain_egrep_fgrep): New rule, the part of the old
  'sc_tests_plain_egrep_fgrep' rule that checked for use of
  'fgrep' and 'egrep' in *.am and *.m4 fragments (rather than
  in test scripts).
  (syntax_check_rules): Update.
  * t/dist-formats.tap: Fix bad use of "make" instead of "$MAKE"
  revealed by the extra coverage.
  * t/cond5.sh, t/auxdir-autodetect.sh: Cosmetic changes to avoid
  spuriously triggering the maintainer checks due to the
  enhanced coverage.
