I'll attempt to "just drop" meta-gplv2, then. However I see that there are other dependencies on readline too, i.e. it might be easier to just replace the existing 5.2 version in meta-gplv2 with 8.2 from here:
No. You cannot 'just replace' it, as they are under different
licenses, and meta-gplv2 specifically collects versions under gpl
version 2 only. specifies:

"When we say that GPLv2 and GPLv3 are incompatible, it means there is no
legal way to combine code under GPLv2 with code under GPLv3 in a single
program." - What is a single program though? Readline would still be a
single program within the bitbake build, would it not? I'm not
"stealing" nor editing its code but compile it as is.
Combining gpl2 and gpl3 is not an issue here. The issue is that if you
ship gpl3 items to users as a part of some product, you have an
obligation to allow them to change those items and install the changes
on the product. This is why meta-gplv2 was created: it effectively
reverts everything that is nowadays gpl3 licensed to older versions
which are still under gpl2.

Single program is commonly interpreted as a runtime process with its
own virtual address space. E.g. all linked libraries, even 3rd party
ones, are a part of the single program.
