aclocal: AC_CONFIG_MACRO_DIRS: work around autom4te option parsing bugs The autom4te program coming with autoconf 2.68 and earlier had a bug which caused the "-" command line argument (with which we tell it to read some input from from standard input) to aways be pushed at the *end* of the command line, regardless of where the user specified it (that bug was fixed by autoconf commit 'v2.68-120-gf4be358', "getopt: new Autom4te::Getopt module"). This broken semantics conflict with our usage in aclocal, where we need to pass some input to the invoked autom4te program early, and have so far been using the stdin to do so. Now we start using an external file instead. * m4/internal/ac-config-macro-dirs.m4: New file, contain a fallback definition of the AC_CONFIG_MACRO_DIRS macro for older autoconf releases. * aclocal.in (trace_used_macros): When invoking autom4te, use that file instead of "abusing" standard input. * Makefile.am (dist_automake_ac_DATA): Rename ... (nobase_dist_automake_ac_DATA): ... like this. Add 'm4/internal/ac-config-macro-dirs.m4' to it. * t/aclocal-acdir.sh: Adjust to avoid spurious failures.
