[PATCH 08/19] aclocal.m4, configure.in: Fix invisible Autoconf results.

[G. Branden Robinson]

...when $DESTDIR is empty or unset.
...when AC_TRY_COMPILE decides no etip.h workaround is required.
...when determining default loader flags.
...when determining an extra suffix for the library name.
...when determining list of compiled-in fallback terminal descriptions.

Also drop attempted expansion of $DESTDIR inside help string.  This
doesn't work with Thomas Dickey's version of Autoconf; a later version
supporting AS_HELP_STRING, and its use, would be necessary to do that.
