Subject: [PATCH] Add riscv64 support
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.
