[PATCH 0/2] use AM_TESTS_ENVIRONMENT Automake variable

[Mathieu Lirzin]

Hello,

Since 2011 Automake TESTS_ENVIRONMENT variable is reserved for the
user unless the “older (and discouraged) serial test harness” is used.
See:

  
https://www.gnu.org/software/automake/manual/automake.html#index-AM_005fTESTS_005fENVIRONMENT

The first patch makes use of the new AM_TESTS_ENVIRONMENT
developer-reserved variable, and the second one adds a ‘syntax-check’
to ensure no rule to preach the good news!  ;)

Thanks,

Mathieu Lirzin (2):
  prefer AM_TESTS_ENVIRONMENT to TESTS_ENVIRONMENT
  maint.mk: prohibit user reserved make flags
