Hi, thanks for your efforts. I only saw your message now as you mailed
1024636-quiet at bugs.debian.org which is not forwarded to the maintainer.
Please use just 1024636 at bugs.debian.org in the future.

If the files are from a native build that passed the Perl test suite
during the build, that's totally acceptable. My concern was about the
previous hand crafted cross config files that looked like nobody had
ever tested them at all. For such hand crafting, I suppose a minimal
test would be to install the cross built binary perl packages on an
actual loong64 host and run 'perl -V' or something like that.

However, I'm afraid we have missed the train here: your patch is for
Perl 5.36 but we're now moving to 5.38 (with perl_5.38.2-2 building in
Debian unstable right now.) It makes little sense to include the 5.36
config files now, so unfortunately you'll have to redo the process with
the 5.38 package.

Apologies for the awkward process. It's all workarounds for perl upstream
not supporting cross configuration properly due to lots of historical
baggage.
