Not so, unless I'm vastly confused.

Corinna is trying to generate --host=i686-mingw32 tools, with a
different --target.  This requires at least a --target=i686-mingw32
compiler coming from elsewhere.  That compiler can build the
--host=i686-mingw32 libraries, and usually should.

This is more like adding support for using the in tree newlib with an
arm-linux compiler so that you could build GCC to run on arm-linux,
without having to install an arm-linux C library first.  That's why
I'm dubious about the value.  But maybe Corinna has some good example
of when you want to do this?
