+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

+Bug 1769631 - Remove 'U' from 'mode' parameters for various 'open' calls to ensure Python3.11 compatibility r=firefox-build-system-reviewers,glandium
+
+The 'U' flag represents "universal newline". It has been deprecated
+since Python3.3. Since then "universal newline" is the default when a
+file is opened in text mode (not bytes). In Python3.11 using the 'U'
+flag throws errors. There should be no harm in removing 'U' from 'open'
