[compiler-rt][Sanitizer] Link sanitizer libs with -latomic on SPARC

When building on Linux/sparc64, the 32-bit `libclang_rt.asan.so`,
`libclang_rt.ubsan_minimal.so`, and `libclang_rt.ubsan_standalone.so`
failed to link with undefined references to 64-bit atomics, which `clang`
cannot inline.  Even D130569 <https://reviews.llvm.org/D130569> didn't help
because those libraries are linked with `-nodefaultlibs`, so dependent
libraries need to be added explicitly.

That's what this patch does.

Tested on `sparc64-unknown-linux-gnu` and `sparcv9-sun-solaris2.11`.
