Hi,

I cleaned the previously built sources and re-triggered the rust builds.
The earlier data was based on testing with the older builds.
After cleaning and re-building, the build time and FS usage are now comparable
to rust v1.85.1.

Here is the new data:

rust version	Build time(rust-native)	Build time (rust target)	FS usage (build/tmp/work/core2-64-poky-linux/rust/1.86.0/rustc-1.86.0-src/build)
v 1.85.1	20 mins	33 mins	6.3 G
v 1.86	25 mins	35 mins	6.6 G

I have sent the rust v1.86.0 upgrade here:
