Bug#1059000: mutter : Please add support for loong64

[Jeremy Bícha]

Dandan,

Thank you for the screenshots and testing.

I would prefer to avoid doing further 46.x uploads for mutter; instead
I am working to getting GNOME Shell & Mutter 47 into Debian Unstable
this month.

We are unwilling to completely ignore build test failures. We are
going to need a more targeted fix, possibly only ignoring the 2 tests
that fail.

Here's a snippet from gtk4's debian/rules. Could you try adjusting
this for loong64 and see if running the mutter build with softpipe
avoids the test failures?

ifneq ($(filter mips% powerpc riscv% sparc%,$(DEB_HOST_ARCH_CPU)),)
$(info Disabling use of llvmpipe on this CPU, see
https://bugs.debian.org/993550 and https://bugs.debian.org/1080435)
export GALLIUM_DRIVER=softpipe
endif
