Disable DWARF in linker options for i686-unknown-uefi
This fixes an lld warning: > warning: linker stderr: rust-lld: section name .debug_frame is longer > than 8 characters and will use a non-standard string table See https://reviews.llvm.org/D69594 for details of where the warning was added. This warning only occurs with the i686 UEFI target, not x86_64 or aarch64. The x86_64 target uses an LLVM target of `x86_64-unknown-windows` and aarch64 uses `aarch64-unknown-windows`, but i686 uses `i686-unknown-windows-gnu` (note the `-gnu`). See comments in `i686_unknown_uefi.rs` for details of why. The `.debug_frame` section should not actually be needed; UEFI targets provide a separate PDB file for debugging. Disable DWARF (and by extension the `.debug_frame` section) by passing `/DEBUG:NODWARF` to lld. Tested with: export RUSTC_LOG=rustc_codegen_ssa::back::link=info cargo +stage1 build --release --target i686-unknown-uefi
