Setting prove argument $blib to "-b" for dists with generated .pm files

[zmughal]

In auto.bash, the variable $blib is set based on the checking find blib/arch/ -type f ! -empty.

However, sometimes there are files that are generated at build time that are placed under blib/lib (prove -b), but we still have an empty blib/arch. In this case, the tests fail because they can't find these generated files under lib (prove -l).

I get this issue when building an Alien::Base-based package on Travis-CI.

A work around is to add the line

  - export PERL5OPT="${PERL5OPT}${PERL5OPT:+ }"'-Iblib/lib' # work around for Travis Perl helper (auto.bash $blib) 

before the --auto command.

Perhaps it may be worth documenting this or even just sticking to blib='-b'?

Is this still a problem?
