Bug#1059554: ares: FTBFS: "unknown arch, please specify manually"

[zhangdandan]

Source: ares
Version: 132-1
Severity: wishlist
Tags: ftbfs
User: debian-loonga...@lists.debian.org
Usertags: loong64
Dear maintainers,

Compiling the ares failed for loong64 in the Debian Package 
Auto-Building environment. The error messages is as follows,
```
make[1]: Entering directory '/<<PKGBUILDDIR>>/desktop-ui'
../nall/GNUmakefile:123: *** unknown arch, please specify manually..  Stop.
make[1]: Leaving directory '/<<PKGBUILDDIR>>/desktop-ui'
dh_auto_clean: error: cd desktop-ui && make -j16 distclean returned exit 
code 2
```
The full build log can be found at 
https://buildd.debian.org/status/logs.php?pkg=ares&ver=132-1&arch=loong64.

I have added the loongarch64 support in ares source code.
The ares source package was compiled successfully on my local environment.
Please consider the patch I have attached.
I have also submitted the pull-request to ares upstream, please see 
https://github.com/ares-emulator/ares/pull/1356.
If you have any questions, you can contact me at any time.

thanks,
Dandan Zhang
