It get's me further, but AC_LIBTOOL_DLOPEN fails the same way if
you configure a cross to spu with --disable-shared, so I'm in addition
now trying

*************** AC_PROG_INSTALL
*** 158,164 ****
--- 164,172 ----
  
  # Configure libtool
  #AC_MSG_NOTICE([====== Starting libtool configuration])
+ if x$enable_shared = xyes; then
  AC_LIBTOOL_DLOPEN
+ fi
  AM_PROG_LIBTOOL
  AC_SUBST(enable_shared)
  AC_SUBST(enable_static)
