Thanks for taking the time to review this patch.

1) Root cause and background
   The warning message was traced back to a change discussed in
   https://inbox.sourceware.org/gdb-patches/704078b1-cb70-4b13-a721-0fed502db160@FreeBSD.org/#r.
   However, there is a better way to address the problem directly in the
   current git version, from commit 1304f47d02bfd0b41ebf4c1c6758a6251c29d8a1.

2) Impact of PRSTATUS_SIZE
   PRSTATUS_SIZE is a local definition used only in
   bfd/elfnn-loongarch.c. Its purpose is to act as a guard when handling
   the .note desc that stores register information for the LoongArch64
   backend.
   Without this guard, the default processing path may be taken instead,
   which may lead to inconsistent behavior compared with the dedicated
   LoongArch64 backend logic.

Changes since v2:
  - Rebased on upstream master (GDB 14.1).
  - Updated commit message for clarity.
