The common characteristic of those failures is the command line
handling.

Automake use Perl provided Getopt::Long module to parse the command line
arguments and the version you are using seems to behave differently than
usual.

for example from Automake 1.15.1 build directory the following command
is supposed to work:

--8<---------------cut here---------------start------------->8---
$ t/wrap/automake-1.15 --vers
automake (GNU automake) 1.15.1

--8<---------------cut here---------------end--------------->8---

According to your logs this doesn't work on your system.  My impression
is that those failing tests are checking the edge cases of Getopt::Long
which is system dependent and not the functional behavior of Automake.
As a consequence it seems reasonable to narrow the tests to more
conservative Getopt::Long behaviors.

WDYT?

Sorry for the delay.
