+From 7bfb7f698bf1b86a0996d5ee500bb6e568db2fef Mon Sep 17 00:00:00 2001

+Subject: [PATCH] sdk: fall back to prost-build's own protoc lookup on riscv64
+
+Upstream-Status: Inappropriate [protoc-bin-vendored ships no riscv64 binary; prost-build already honours $PROTOC and falls back to protoc on PATH, so only overriding PROTOC when the vendored lookup succeeds is the whole fix]
+
+protoc_bin_vendored::protoc_bin_path() returns Err on any platform outside
+its small enum of prebuilt targets (x86, x86_64, aarch64, ppc64le, s390x,
+macOS, Windows), and build.rs unwrap()ed it, panicking before prost-build
+ever got a chance to look for a protoc on PATH or via $PROTOC. Only
+setting PROTOC when the vendored lookup succeeds restores that fallback,
+documented in prost-build's "Sourcing protoc" section.
