Currently, we have not supported building with clang, so please install riscv gcc on your building machine and add path of toolchain to env var PATH before continue.
Besides, you may have to update andorid-kernel/common/build.config.riscv64 to set "CROSS_COMPILE" to your own triplet string.
Then you can continue with:
BUILD_CONFIG=common/build.config.gki.riscv64 ./build/build.sh -j $(nproc)
BUILD_CONFIG=common-modules/virtual-device/build.config.virtual_device.riscv64 build/build.sh -j $(nproc)
Now you can find kernel image(Image) and kernel modules(.ko) in andorid-kernel/out/android12-5.10/dist.
