Your config-ml.in change broke cris-axis-elf newlib multilib build

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

...but thanks anyway for your work to update to a newer libtool. 8)

This is a note rather than a PR, though I will enter a PR if the
situation remains for 48h.  The following happened with newlib
as of two days ago (Apr 13 04:15 CET) with gcc in a combined
tree as of 123829 but worked with 123816.  I see nothing in src
that would help (only the config-ml.in change, which is
overwritten by the gcc version).  I guess this would be the same
for all newlib multilib systems.  To repeat, use e.g. the
simtest-howto.html instructions to build, configure with
--target=cris-elf.  Beware of the overlong lines.
