Status and rationale for toplevel bootstrap (was Re: Example of debugging GCC with toplevel bootstrap)

[Richard Kenner]

    So a naiive ./configure && make will configure for host == target ==
    powerpc64 but still (wrongly so in your opinion?)  build stage1 as
    32bit binaries (but defaulting to -m64 code generation now), and the
    following stages will now become 64bit.

That's most *definitely* wrong because we're lying to configure and saying
we're building a native compiler when we're really building a cross-compiler.
We're lying as to what the host is!
