Compilation fails with a rust-lld: error: undefined symbol: memchr error.

To reproduce

• Spawn a ledger-app-dev-tools Docker container and open a terminal inside it.
• git clone https://github.com/LedgerHQ/ledger-device-rust-sdk.git
• git checkout enable-qrcode
• rustup default nightly-2023-11-10-x86_64-unknown-linux-musl
• cd ledger_device_sdk/
• cargo run --target stax.json --package ledger_device_sdk --example nbgl_generic_review

For information, modifying link_wrap.sh as following:

diff --git a/ledger_device_sdk/link_wrap.sh b/ledger_device_sdk/link_wrap.sh
index 31f6cb7..7ba635c 100755

seems to solve the issue 🤔
Needs to be further investigated...

@yogh333 you need to bump sdk versions.
