[PATCH v16 10/10] tests: Add LoongArch to various test cases

[Xiaotian Wu]

I ran the test suite on a 3A5000 desktop, a LoongArch architecture machine,
using Archlinux for LoongArch distro, see https://github.com/loongarchlinux.

Some software versions are:
* linux 6.3.0-rc4
* gcc 13.0.1 20230312
* binutils 2.40
* qemu 7.2.0

The test results of running "make check" with qemu 7.2 are as follows:

=================================
   GRUB 2.11: ./test-suite.log

  # TOTAL: 85
  # PASS:  73

WARNING: Image format was not specified for 
'/tmp/grub-shell.HeTAD8Ty3U/grub.iso' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write 
operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.

TEST FAILURE
FAIL grub_func_test (exit status: 1)

We got 2 errors:

* f2fs_test
The kernel uses 16k pages, causing failures when loading the f2fs kernel module,
see https://github.com/torvalds/linux/blob/master/fs/f2fs/super.c#L4670
This error can be ignored.

* zfs_test
zfs does not support the LoongArch architecture and is not compatible with the
6.3 kernel.
This error can be ignored.

We got 2 failures:

* hfs_test
I use recode 3.7.14-1 on Archlinux, running `recode -l` gives no output 
`MacRoman`,
so we get this error.
On Linux systems that support LoongArch, there is currently no need to use HFS,
so this failure can be ignored.

* grub_func_test
I don't know the reason for this failure. I guess it may be related to qemu's 
edk2.
In the previous review, I was told that the failure here is the expected 
behavior.
So, we can ignore this failure.
