thanks! I tried the patch and it fixes the universal build that broke with
16743db (and make check passes for both architectures). It remains to be 
analysed how useful these universal builds are given the lack of 
optimisations for one of the architectures, but at least they are possible
again, as they were previously.

Please find the configure output attached.

sure, I haven't yet evaluated the meson build system but I plan to do so.
