[FYI] {yacc-work} coverage: test for automake bug#8485 (known regression)

[Stefano Lattarini]

I've pushed the attached patch to yacc-work.  The new testcase
should correctly capture and expose the regression, as it passes
with automake 1.11 and fails with developement (maint, master
and yacc-work) versions of automake.

Regards,
  Stefano
