OpenBLAS RISC-V 64bit support was added in [1] and was renamed to "RISCV64_GENERIC" in [2]. Those commits were first included in OpenBLAS release v0.3.13. This support can now be enabled. With this commit, we can install the library and packages such as GNU Octave on RISC-V platforms. This patch also adjusts the alignment for adding "RISCV64_GENERIC" in Config.in.
