autogen fails to build on i686-linux

Hello,

autogen fails to build on i686-linux like so, for instance on master commit

c9af27d4ca733b20f09019f1465d3e5fdc1ec724:

libtool: compile: gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I../autoopts -DPKGDATADIR=\"/gnu/store/n29inqv3rnwix1jqsxc1gd2yw0q8jkr0-autogen-5.18.16/share/autogen\" -g -O2 -Wno-format-contains-nul -fno-strict-aliasing -Wall -Werror -Wcast-align -Wmissing-prototypes -Wpointer-arith -Wshadow -Wstrict-prototypes -Wwrite-strings -Wstrict-aliasing=3 -Wextra -Wno-cast-qual -g -O2 -Wno-format-contains-nul -fno-strict-aliasing -c libopts.c -fPIC -DPIC -o .libs/libopts_la-libopts.o

cc1: all warnings being treated as errors

The version we package from

https://ftp.gnu.org/pub/gnu/autogen/

dates from 2018. The website

https://www.gnu.org/software/autogen/

has apparently not been updated since 2015.

I wonder if we had not better drop this apparently unmaintained software,

but it has quite a lot of dependents:

Building the following 1275 packages would ensure 2489 dependent packages are rebuilt

Thanks a lot, this looks like a good fix. I have just pushed it.
