Dear maintainers,
Compiling the rust-lv2-sys failed for loong64 in the Debian Package
Auto-Building environment.
The error log is as follows,
```
error: The targeted computer architecture is not supported by rust-lv2!
--> src/linux/unsupported.rs:1:1
......
```
The full build log can be found at
https://buildd.debian.org/status/logs.php?pkg=rust-lv2-sys&ver=2.0.0-1&arch=loong64.
I have added the loongarch64 support to the rust-lv2-sys source package.
And built successfully on my local ENV.
Please consider the patch I attached.
I also duploaded the below packages to debian ports.
```
dpkg-deb: building package 'librust-lv2-sys-dev' in
'../librust-lv2-sys-dev_2.0.0-1+loong64_loong64.deb'.
dpkg-genbuildinfo -O../rust-lv2-sys_2.0.0-1+loong64_loong64.buildinfo
dpkg-genchanges -sa -O../rust-lv2-sys_2.0.0-1+loong64_loong64.changes
dpkg-genchanges: info: including full source code in upload
dpkg-source --after-build .
```
Meanwhile, I have submitted a pull request to upstream rust-lv2-sys.
Please see https://github.com/RustAudio/rust-lv2/pull/120.
If you have any questions, you can contact me at any time.
thanks,
Dandan Zhang
