Dear maintainers,
We need to add loongarch64 support in gnss-sdr.
Please consider the patch I have attached.
If the maintainer sees no problem with the patch, can also submit to
upstream.
In addition, I give feedback on an error when compiling on my local ENV,
for example:
```
......
/usr/include/gnuradio/io_signature.h:194:73: error: ‘string_view’ is not
a member of ‘std’
194 | struct GR_RUNTIME_API fmt::formatter<gr::io_signature> :

| ^~~~~~~~~~~
/usr/include/gnuradio/io_signature.h:194:73: note: ‘std::string_view’ is
only available from C++17 onwards
/usr/include/gnuradio/io_signature.h:194:73: error: ‘string_view’ is not
a member of ‘std’
/usr/include/gnuradio/io_signature.h:194:73: note: ‘std::string_view’ is

/usr/include/gnuradio/io_signature.h:194:84: error: template argument 1
is invalid
194 | struct GR_RUNTIME_API fmt::formatter<gr::io_signature> :
formatter<std::string_view> {

```
If you have any questions, you can contact me at any time.
Thanks,
