[PATCH v14 00/26] Add LoongArch linux-user emulation support

[Song Gao]

Based-on: <20220106074740.1754661-1-gaosong@loongson.cn>

Hi all,

This series only support linux-user emulation.
More about LoongArch at: https://github.com/loongson/

The latest kernel:
  * https://github.com/loongson/linux/tree/loongarch-next

Patches need review:
  * 0018-linux-user-Add-LoongArch-specific-structures.patch
  * 0019-linux-user-Add-LoongArch-signal-support.patch

Changes for v14:
  * Rebase;
  * Update README, use new clfs-system/cross-tools test.

V13:
https://patchew.org/QEMU/1638610165-15036-1-git-send-email-gaosong@loongson.cn/

Please review! Thanks.
