* tests/defs (configure.in): Use credible AM_INIT_AUTOMAKE

* tests/defs (configure.in): Use credible AM_INIT_AUTOMAKE
arguments.
Don't run AC_ARG_PROGRAM another time, it is required by
AM_INIT_AUTOMAKE.
* tests/aclocal.test: Work on the default configure.in
* tests/config.test (configure.in): Don't AC_ARG_PROGRAM.
First AM_INIT_AUTOMAKE, then AM_CONFIG_HEADER.
Be realistic in testing: AC_INIT is required for Autoconf.
Broken so called optimized tests break trace handling.
