`--prefix /foo' mishandled in sub-configure invocation

[Alexandre Duret-Lutz]

I've found the following bug when configuring AutoGen
with a configure generated by Autoconf 2.52e (2001-10-26).

~/projs/cvs/autogen/autogen % ./configure --prefix ~/usr
[... skiping until we configure the subdirectory ...]
configure: configuring in snprintfv
configure: running /bin/sh './configure' --prefix=/home/adl/usr  /home/adl/usr 
--enable-snprintfv-convenience --cache-file=/dev/null --srcdir=.
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: /home/adl/usr
[...]

Note the prefix argument (/home/adl/usr) appears twice in the
sub-configure invocation.
