[Buildroot] [git commit branch/next] package/erlang: risc-v should only add risc-v

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=76e64a175aef5cfbdf24bd457f3568b4ba159b6f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

This restricts the Erlang RISC-V update from
0bab8c1089983a4b5f0f2acfe5cad77b02d6f654 to only enabling RISCV_64
rather than enabling builds on all platforms with toolchains that
include atomics.

This fixes build errors on SPARCv8 and other platforms that look like
this:

/tmp/ccD9Q9F7.s: Assembler messages:
/tmp/ccD9Q9F7.s:230: Error: Architecture mismatch on "cas [%g3],%g2,%g1".
/tmp/ccD9Q9F7.s:230: (Requires v9|v9a|v9b|v9c|v9d|v9e|v9v|v9m|m8; requested architecture is v8.)
