First thank you, Rene, I did get some *porting* work done with your
help. As you know, the bridge UNO part code will cast me more time to
understand. So I update the status about libreoffice port to riscv64 on
Debian. This is useful if anyone has interesting to try it.

To build libreoffice package on riscv64 arch, you need apply the
*patch*[0] and the d/rules that was descripted in the mail thread:

Except for the code under bridges/source/cpp_uno/gcc3_linux_riscv64/, 
other codes should be referenced. The code under 
bridges/source/cpp_uno/gcc3_linux_riscv64/ is the core of libreoffice 
supporting riscv, which will support riscv native for libreoffice.

And now I agree with John said, maye it will get more help from
libreoffice upstream. So, Rene, please do not mind if I am ccing the
libreoffice people. At least, I wish people tell me how to start it:)
