(AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check

Add test for AS_BASENAME.
* lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
added test. It now correctly handles /1/2/3/, returning '3' not ''.

4m.

the time stamps.

We only need PERL.
* tests/atspecific.m4, tests/tools.at: Passing --localdir is
indeed related to running the test suite, while passing

classified as an Autoconf macro.

Rather, pass autoconf_dir to m4.
