cargo: Work around host system library conflicts
cargo ends up running target-rust-ccld with LD_LIBRARY_PATH set to libdir but not
base_libdir which breaks the SDK. You see errors like:
/bin/sh: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
On such a system, this would fail:
LD_LIBRARY_PATH="<path>/testimage-sdk/sysroots/x86_64-pokysdk-linux/usr/lib" cargo build
but this would work:
LD_LIBRARY_PATH="<path>/testimage-sdk/sysroots/x86_64-pokysdk-linux/usr/lib:<path>/testimage-sdk/sysroots/x86_64-pokysdk-linux/lib" cargo build
so wrap cargo with both paths in LD_LIBRARY_PATH.
The error depends on the versions of the host system, it reproduced on tumbleweed-ty-3.
