Enable the media / V4L2 / uvcvideo kernel stack so a USB camera exposes
/dev/videoN for majestic's usbcam second-camera path.
To fit the 8M NOR (2M kernel / 5M rootfs) without dropping any sensor
library, uvcvideo and the videobuf2 framework are built INTO the kernel
(=y) instead of shipped as rootfs modules: the kernel partition had ~55 KB
of spare room while the rootfs was tight, so ~44 KB of weight moves from
rootfs to kernel. Resulting images: uImage 2022.8 KB / 2048 KB (25 KB
spare), rootfs squashfs 5080 KB / 5120 KB (40 KB spare).
GSPCA -- a separate driver for non-UVC webcams, pulled in by "default m
depends on VIDEO_V4L2" -- is disabled.
No kernel patch is carried: mmap capture works on stock uvcvideo once
majestic aligns its mmap() prototype with this MMAP_MUSL build's
uint32_t-offset shim (a userspace fix), so the earlier read()/fileio
uvcvideo patch is not needed.

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.

Add BR2_PACKAGE_HISILICON_OPENSDK=y to 9 hi3516cv200-family profiles
that were missing it. These boards will now get open_ modules built
from openhisilicon source instead of vendor-only blobs from osdrv.
