Version: 2:20.2+dfsg-4

Dear maintainers,

When compiling the package kodi for loong64 in the Debian Package 
Auto-Building environment [1], the error messages is as follows.
......Omit
The following tests FAILED:
    130 - TestSystemInfo.GetKernelBitness (Failed)
    131 - TestSystemInfo.GetKernelCpuFamily (Failed)
    132 - TestSystemInfo.GetXbmcBitness (Failed)
    137 - TestSystemInfo.GetBuildTargetCpuFamily (Failed)
Errors while running CTest
make[2]: *** [Makefile:74: test] Error 8
make[2]: Leaving directory '/<<PKGBUILDDIR>>/obj-loongarch64-linux-gnu'
dh_auto_test: error: cd obj-loongarch64-linux-gnu && make -j16 test 
ARGS\+=--verbose ARGS\+=-j16 returned exit code 2
......Omit

The full compilation log can be found at [2].

I have added loongarch64 support in the SystemInfo.cpp file.
Please consider the patch I have attached.
Would it be possible to include the support for LoongArch in the next 
upload?
If you have any questions, you can contact me at any time.
