Test 246: Non-literal AC_CONFIG_SUBDIRS FAILED (torture.at:1738) in 2.67

[Bernhard Rosenkraenzer]

Hi,
the autoconf 2.67 "make check" test 246: Non-literal AC_CONFIG_SUBDIRS
(torture.at:1738) fails if any slightly bogus files are installed in
/usr/share/aclocal.

e.g. openhbci comes with an aclocal m4 file with an underquoted
definition, causing the test to fail:


246. torture.at:1708: testing Non-literal AC_CONFIG_SUBDIRS ...
./torture.at:1712: aclocal --version || exit 77

Probably the test shouldn't use aclocal --warnings=error (or somehow
prevent aclocal from reading everything in /usr/share/aclocal).
