Looks like it'd also get rid of the bogus
-bE:/usr/opt/perl5/lib64/5.28.1/aix-thread-multi-64all/CORE/perl.exp we're
we're picking up on AIX (we had a thread about filtering that out, but I've only
done so inside the meson patch, round tuits).

So +1 from that front.

Maybe a daft question: Why do want any of the -l flags other than -lperl? With
the patch configure spits out the following on my debian system:

checking for CFLAGS to compile embedded Perl... -DDEBIAN
checking for flags to link embedded Perl... -L/usr/lib/x86_64-linux-gnu/perl/5.34/CORE -lperl -ldl -lm -lpthread -lc -lcrypt

those libraries were likely relevant to build libperl, but don't look relevant
for linking to it dynamically. Statically would be a different story, but we
already insist on a shared build.
