  tests: simplify checks for some expected variables values in Makefiles
  
  Do so by using our custom 'is' auxiliary script rather than grepping
  the output from make.  This is more natural, more robust, and often
  shorter to write.
  
  Unfortunately, we can't do that in all cases: sometimes we really need
  to match the content of a variable against a regular expressions, and
  we can't know nor are interested in its exact value.
  
  This is basically a follow-up on commit v1.11-1830-g96401cb of
  2012-02-08 (tests: better way to compare lists in Makefile rules).
  
  * t/subst-no-trailing-empty-line.sh: Adjust.
  * t/pluseq10.sh: Likewise.
  * t/check5.sh: Likewise, and enhance a little while at it.
  * t/check7.sh: Likewise.
  * t/exeext.sh: Likewise.
