Confirmed.

To reproduce on systems that do not need_lib_prefix:
  configure
  $EDITOR ./libtool  # set need_lib_prefix=unknown
  make check TESTS='tests/mdemo-static.test tests/mdemo-make.test
                    tests/mdemo-exec.test'

results in the "invalid loader" showing up in the logs (see at end).
Presumably because the preopen loader (at least) ignores the needed
"lib" prefix.


By the way: does BeOS need the "lib" prefix for modules at all?
To test a hypothetical "no" answer, I think this should work:
  configure
  $EDITOR ./libtool  # set need_lib_prefix=no
  make check TESTS='tests/mdemo-shared.test'
  $EDITOR tests/mdemo/libtool  # set need_lib_prefix=no
  make check TESTS='tests/mdemo-make.test tests/mdemo-exec.test'

I guess both of these issues eventually need tests as well..

By the way 2: what about config.log and the result new HEAD
testsuite?  Even if all the ltdl tests fail, the others are
still still valuable.  (Surely it'd be good to rerun the ltdl
tests when a fix for this particular issue is applied.)

Cheers,
Ralf
