* lib/am/configure.am (%MAKEFILE-IN%): If Makefile.in is rebuilt
because of one of configure's dependencies, run automake without
argument to update the whole tree at once.  Depend upon
%CONFIGURE_DEPS%.
(%MAKEFILE%): If Makefile is rebuilt because config.status has
been updated, run config.status without arguments.
* automake.in (scan_autoconf_traces): Prepend $(top_srcdir)
before all files in @configure_deps.
* tests/subdir5.test: Modernize configure.in, make sure
maude/Makefile was actually created, and exercise %CONFIGURE_DEPS%.
* tests/subdir8.test: New file.
* tests/Makefile.am (TESTS): Add subdir8.test.
