Steps to reproduce

• add packagegroup to TOOLCHAIN_HOST_TASK by TOOLCHAIN_HOST_TASK:append = " packagegroup-rust-cross-canadian-${MACHINE}"
• bitbake <rust based (distro) image> -c do_populate_sdk
• install sdk
• source sdk
• go to your project and run cargo build

i have no idea why but it looks like the linker likes to load /usr/lib/gcc/x86_64-linux-gnu/11/liblto_plugin.soinstead of /opt/beet/2022.04/sysroots/x86_64-beetsdk-linux/usr/libexec/aarch64-beet-linux/gcc/aarch64-beet-linux/9.3.0/liblto_plugin.so

CMake and so on work as expected but cargo doesn't. hope you can help!

I wonted to chime in on this. I can build using bitbake ok, but for developing my package I obviously prefer using cargo build directly with the SDK-based toolchain. But this fails with similar issues. I'v looked into the cargo bbclass but didn't find anything obvious.

It appears to me as if cc is the systems gcc /usr/bin/gcc instead of the cross-compiler gcc.

Any suggestions are very welcome.
