OpenIPC/firmware PR #2162 (merged 2026-05-30) dropped the legacy BR2_TOOLCHAIN_EXTERNAL_GCC_8=y + BR2_GCC_VERSION_LEGACY=y block from its 18 ARM defconfigs and ships gcc 13.3.0 to those platforms now. OpenIPC/builder's per-device and common Goke defconfigs still pinned gcc 8, so every Goke job in the 2026-06-02 nightly Build run failed at the toolchain stage with: Incorrect selection of gcc version: expected 8.x, got 13.3.0 make[1]: *** [toolchain-external-custom/.stamp_configured] Error 1 Mirror #2162 across the 24 affected defconfigs (8 common + 16 per-device). No other defconfig content changes. Unrelated 4 Sigmastar rootfs-overflow failures in the same nightly are tracked separately.
