I've finally started hitting against this problem.

I've added the lines

use lib '.';
use Texinfo::ModulePath (undef, undef, 'updirs' => 2);

to all the tests. The first adds . to @INC so that Texinfo::ModulePath
can be found. Texinfo::ModulePath checks top_srcdir.

I haven't tested what happens with out-of-source builds yet, but I
expect that they would work.
