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

Some userland programs in the BPF test suite, e.g. urandom_read, is
missing cross-build support. Add cross-build support for these
programs

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

The uprobe_multi program was not picked up for the gen_tar target. Fix
by adding it to TEST_GEN_FILES.
