Support for position independent code (PIC)

[benhansen-io]

I would like to use espressif/elf_loader to load an elf file with Rust code on the esp32s3 (xtensa) however elf loader currently requires position independent code. When I try to compile Rust code with the esp-rs compiler using the rust flag: -C relocation-model=pic

I get the following error message:

LLVM ERROR: PIC relocations is not supported
error: could not compile `core` (lib)

PIC is dependent solely on LLVM support, could you open the issue under https://github.com/espressif/llvm-project instead?

Done. Issue is espressif/llvm-project#106
