  tests: avoid FreeBSD make VPATH issues in more tests (see bug#7884)
  
  See also similar change 'v1.11-755-g818bc40' of 07-02-2012,
  "tests: work around bug#7884 in many yacc/lex tests".  The
  rationale for this change is basically the same.
  
  * tests/lex-lib-external.test: Use "yl_distcheck" instead of
  bare "$MAKE distcheck" to avoid extra failures caused by
  automake bug#7884.
  * tests/lex-noyywrap.test: Likewise.
  * tests/lex-libobj.test: Likewise.
  * tests/man6.test: This test suffers from the same FreeBSD make
  incompatibility in VPATH handling that is the source of automake
  bug#7884.  Since this is caused by rules that are defined in the
  Makefile.am by the test itself, rather that being generated by
  automake, the best thing to do is to skip this test if we detect
  the presence of said make incompatibility (through the function
  'useless_vpath_rebuild').
  * tests/man8.test: Likewise.
