* tests/extra-portability.test: Redefine `$AUTOMAKE' to ensure we
have complete control over the automake options. Extend by using
also a setup where no `portability' warning is present (only an
`extra-portability' warning is). Other minor extensions. Remove
some redundant, verbose comments about the expected diagnostic.
