Modifying a test apparently requires me to have the same exact Autoconf
version (2.68) as you did. What an annoyance! I have to proceed like this:

1. On a machine with autoconf 2.68:
   - Unpack a fresh automake-1.11d directory.
   $ ./configure; make                 # This is necessary to build 'automake'.
   - Then only! change t/lex-libobj.sh
   $ make                              # This uses the built 'automake'.
   $ make distclean
2. Copy this directory to the target machine (without autoconf 2.68).
3. $ ./configure; make
   $ make check TESTS=t/lex-libobj

Result: it still fails:

cc  -g -O2   -o foo foo.o -L . yywrap.o
ld: in ., can't map file, errno=22
collect2: ld returned 1 exit status
make: *** [foo] Error 1
+ exit_status=2
+ set +e
+ cd /Users/bruno/data/build/multibuild-2074/macosx/automake-1.11d
+ test no = yes
+ case $am_explicit_skips in
+ test 2 -eq 0
+ keep_testdirs=yes
+ am_keeping_testdirs
+ case $keep_testdirs in
+ return 0
+ set +x
lex-libobj: exit 2

But setting LEXLIB to just whitespace makes the test succeed:

How would I do this?
