smokeping is tripping a new warning in perl 5.38:
https://perldoc.perl.org/perl5380delta#New-Warnings

Making all in doc
gmake[1]: Entering directory '/pobj/smokeping-2.8.2/smokeping-2.8.2/doc'
PERL5LIB=/usr/local/libdata/perl5/site_perl /usr/bin/perl -I../thirdparty/lib/perl5 -I../lib -mSmokeping -e 'Smokeping::main()' -- --makepod Smokeping::probes::AnotherCurl > Smokeping_probes_AnotherCurl.pod
Unknown locale category 4 at ../lib/Smokeping.pm line 40.
Segmentation fault (core dumped)

Not sure how to work around this, clearly it shouldn't be segfaulting
either though.
