Subject: [PATCH] Rewrite cargo-host-linker in python3

Mozjs compile failed with this failure:
/bin/sh: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /build/tmp-glibc/work/corei7-64-wrs-linux/mozjs/91.1.0-r0/recipe-sysroot-native/usr/lib/libtinfo.so.5)

Root Cause:
cargo-host-linker has /bin/sh as it's interpreter, but cargo run the cmd
with LD_LIBRARY_PATH set to recipe-sysroot-native. The host /bin/sh links
libtinfo.so.5 under recipe-sysroot-native, which needs higher libc. But
host libc is older libc. So the incompatible problem occurred.

Solution:
rewrite cargo-host-linker in python3

Upstream-Status: Inappropriate [oe specific]
