1. Configure gbuild
2. Add UNO Bridge for riscv64
Till now base function works well on riscv64. The bridgetest has passed.
Test on Debian, Gentoo and openEuler.
Credits:
- Heiher <r@hev.cc> and Stephan Bergmann <sbergman@redhat.com>
The riscv64 bridge implementation refers to mips64 and
AArch64 bridges.
- Bo Yu <tsu.yubo@gmail.com> configures gbuild for riscv64.
- WANG Xuerui <xen0n@gentoo.org> provides lots of guiding tips.
