Subject: [PATCH] riscv only supports split_debuginfo=off for now

Disable packed/unpacked options for riscv linux/android.
Other riscv targets already only have the off option.

The packed/unpacked options might be supported in the future.
See upstream issue for more details:
https://github.com/llvm/llvm-project/issues/56642

Fixes #110224
