The build time differences on my machine are as follows:

rust version
	rust upstream builds
	rust-native (yocto build)
	rust target (yocto build)
v1.85.1
	10 mins
	20 mins
	33 mins
v1.86.0
	22 mins (with "lld" and "use-lld" set to "false")
30 mins (with default settings i.e lld = true)

	31 mins (with "lld" and
"use-lld" set to "false") 	43 mins (with "lld" and
"use-lld" set to "false")

Note: The machine being used is a shared resource and fairly busy. Build 
times may differ due to other user's builds.


The FS usage is as follows:

Rust version
	rust upstream builds
	Yocto rust builds 
(build/tmp/work/core2-64-poky-linux/rust/1.86.0/rustc-1.86.0-src/build)
v1.85.1
	4.6 G
	6.3 G
v1.86.0
	15 G
	8.8 G

The latest rust v1.86.0 upgrade changes are available at:
https://git.yoctoproject.org/poky-contrib/log/?h=harish/rust_1.86.0_v2
