[Buildroot] [git commit branch/2021.02.x] package/botan: add support for riscv32

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=2f9552bb50b216a2be071bd4af266ecd2db6e532
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2021.02.x

Backport an upstream patch to add support for riscv32. Although this is
a new feature (new arch support), this is an upstream commit, so we can
expect it to be available in a future release.

Fixes:
