> This is v2 of this patch, with these changes:
>   1. ‘with-toolchain’ is replaced by ‘with-c-toolchain’ everywhere,
>      with the understanding that it’s about the C/C++ toolchain
>      in practice.  In the end I’m sympathetic with the argument
>      that C/C++ don’t have a monopoly on toolchains.  ;-)
>   2. ‘--with-c-toolchain=PACKAGE=TOOLCHAIN’ rebuilds not just
>      PACKAGE with TOOLCHAIN, but also everything above PACKAGE
>      with TOOLCHAIN (in v1, only PACKAGE was rebuilt with TOOLCHAIN
>      but everything above it had to be rebuilt anyway.)
>      The main motivation here is to reduce the changes that we’re
>      introducing ABI incompatibilities that users would have to work
>      around by passing on ‘--with-c-toolchain’ for each package in
>      the chain.  I think it also more closely matches user
>      expectations: when you see things are being rebuilt, you’re
>      likely to think that’s because they’re rebuilt with the new
>      toolchain, not the default one.
> Feedback welcome!
