--localdir backwards compatibility

[Niels Möller]

The renaming of --localdir to --prepend-include is annoying when
trying to keep a configure.in compatible between 2.13 and more modern
versions. To make it less painful, I patched in some backwards
compatibility to my local version of autoconf-2.57. Seems to work fine
for me.
