Sadly things have not worked out any better.   :(

Configure still looks nice :

All the usual baseline tools are around. Also gmp/mpfr/mpc are extracted

However a while later we see make bootstrap fail :

So that sort of looks the same but also I am not sure what is needed 
here.  As usual the package libc6-dev provides :

     /usr/include/arm-linux-gnueabihf/bits/libc-header-start.h

However that is in a weird place. Do I need host/target/foobar etc?
