Seems this came with

commit 5fdf6e90221900a85cd3091bd2755e41fc230d4d
Author: Paul Evans <[email protected]>
Date:   Mon Jan 22 22:29:39 2024 +0000

    Add builtin::inf and builtin::nan


https://github.com/Perl/perl5/commit/5fdf6e90221900a85cd3091bd2755e41fc230d4d

As there is configury available for some aspects of FP NANs / INFs, I
think that this was just an oversight and not a design decision to
drop anything except IEEE math.  Cf. d_double_style_vax,
d_double_has_inf and d_double_has_nan.

For now, I just started a build with reverting that patch. Let's see
where this takes us to...
