Not sure what is causing this on a Linux armv7 32-bit machine but I have
libc6-dev installed and that provides :

But this is not a standard header location, so GCC won't look there.
You need to use --enable-multiarch to use the Debian MultiArch directory
layout.
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
in the source tree as per normal.

Wait, what? You said "gmp/mpfr/mpc are extracted in the source tree as
per normal" so why are you telling GCC to get them from /opt/bw?
I have gone both directions and used the sources for those in tree as
well as included and it seems to have nothing at all to do with the real
problem.
Xi Ruoyao is sending replies that you're apparently not receiving, see

I think my mail server has gone into full rogue mode with spamassassin
and that is the issue.
In any case I see :
