autoreconf: cope with empty AC_CONFIG_SUBDIRS (bug 110331)

Commit 41edf99f9515f3f83398428c39d79e11266a5a0d made all Perl warnings
fatal.  This caused autoreconf to crash on packages that call
AC_CONFIG_SUBDIRS with no arguments. They probably shouldn’t do that,
but we shouldn’t crash if they do.

Problem reported by Ross Burton.

* bin/autoreconf.in (autoreconf_current_directory):
  Convert undef to '' before attempting to split it.
* tests/torture.at (Empty AC_CONFIG_SUBDIRS): New test.
