Subject: [PATCH bpf-next 0/3] selftest/bpf, riscv: Improved cross-building support

From: Björn Töpel <[email protected]>

Yet another "more cross-building support for RISC-V" series.

An example how to invoke a gen_tar build:

| make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- CC=riscv64-linux-gnu-gcc \
| HOSTCC=gcc O=/workspace/kbuild FORMAT= \
| SKIP_TARGETS="arm64 ia64 powerpc sparc64 x86 sgx" -j $(($(nproc)-1)) \
| -C tools/testing/selftests gen_tar

selftests/bpf: Add cross-build support for urandom_read et al
selftests/bpf: Enable lld usage for RISC-V
selftests/bpf: Add uprobe_multi to gen_tar target

Subject: [PATCH bpf-next 2/3] selftests/bpf: Enable lld usage for RISC-V

From: Björn Töpel <[email protected]>

RISC-V has proper lld support. Use that, similar to what x86 does, for
urandom_read et al.
