[PATCH v2 1/1] bfd/loongarch: set PRSTATUS_SIZE=0x1e0 to match kernel's struct elf_prstatus size

[lijian1@kylinos.cn]

From: lijian1 <lijian1@kylinos.cn>

If PRSTATUS_SIZE is incorrect on LoongArch64, BFD cannot properly handle
core files generated on this architecture.  As a result, GDB emits repeated
warnings during core analysis such as:

  warning: Unexpected size of section `.reg/3925' in core file.

This happens because the default BFD handler fails to synthesize the `.reg` section correctly.

With the correct PRSTATUS_SIZE value defined in loongarch_elf_grok_prstatus
(elfnn-loongarch64.c), GDB successfully generates LWP threads without the
above warnings, and core analysis proceeds normally.
