[gentoo-dev] [PATCH] rust-toolchain.eclass: support bootstrapping armv5te

[David Michael]

This adds support for using system-bootstrap to build Rust for the
armv5tel profile.  It does not add binary bootstrap compilers.

Hi,

I have an ARM9 chip that I'd like to be able to target for Rust
packages.  Things are getting masked in the armv5tel profile due to it
not having Rust binaries.  Can we start fixing this?

I've bootstrapped armv5te Rust by cross-compiling it, and it seems to
work.  I can send my ebuild changes if anyone wants to build their own
armv5te compiler, but the eclass should at least define its default
builtin target so that it can be built with USE=system-bootstrap.

Thanks.

David
