Rust's internal LLVM requires zlib and zstd compression libraries when
building rustc_codegen_llvm and other compiler components.
Without these dependencies, building Rust for target fails
with linker errors:

  error: linking with `target-rust-ccld` failed: exit status: 1
  = note: undefined reference to `compress2'
  = note: undefined reference to `uncompress'
  = note: undefined reference to `ZSTD_decompress'
  = note: undefined reference to `ZSTD_isError'
  = note: undefined reference to `ZSTD_compress2'
  = note: undefined reference to `crc32'

This manifested in oe-selftest failure on qemuppc:
  oe-selftest -r rust.RustSelfTestSystemEmulated.test_rust

Additionally, this was observed while testing with other targets as well.
