building the rust toolchain with this crate

[gottaeat]

a quick google search brings up failed attempts of trying to build the rust toolchain with mimalloc, albeit with a different crate which has stopped receiving commits after 2019.

i was wondering if building the toolchain with this crate via doing something similar to https://github.com/rust-lang/rust/pull/62340 is possible.

thanks for your work.

I actually investigated this last weekend. I think some work needs to be done on the mimalloc side to improve their override support.
