The current version of OpenBLAS (v0.3.24) supports the
RV64 architecture. With this update, 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.

Hi Yu,

Thanks for the patch!

I think it would be better to record in the commit log when the RISC-V
support was added. For example:

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.

If you can, please send a v2 updated patch.

I also successfully tested this patch on branch master at
commit 20c023a, by adding in qemu_riscv64_virt_defconfig a Bootlin
toolchain and OpenBLAS with its tests. So you can also add:
