[lucize]

with the new update, cross compile doesn't work anymore:

@ndilieto tried the last patch and it seems that I stil can't compile it

Not sure about openwrt, but in buildroot patching configure.ac requires extra care to insure that autoreconf runs after the patch is applied. Please check https://patchwork.ozlabs.org/project/buildroot/patch/20240220195007.380433-1-fontaine.fabrice@gmail.com/

adding autoreconf fixes the issue
thanks!
