As a stopgap solution, I would try adding an "_LT_DECL_SED" just above 
the "if test "${use_libtool}" = yes; then" line.  This would be no big 
deal compared to the LIB_AC_PROG_GCC hacks currently used by newlib.

However, I think the right way to do it is to mimic what the target 
libraries in the gcc tree do: using AC_NO_EXECUTABLES and always using 
libtool.  I can try to do so in the arm-elf configuration I use at work, 
if it is okay to commit Steve's patch with the temporary measure above.
