Not sure what is causing this on a Linux armv7 32-bit machine but I have
libc6-dev installed and that provides :
# ls -lapb /usr/include/arm-linux-gnueabihf/bits/libc-header-start.h
This is a reasonable little Debian machine :
root@io:~# uname -a
Linux io 4.4.194 #52 SMP Tue Oct 26 08:35:58 UTC 2021 armv7l GNU/Linux
root@io:~#
root@io:~# cat /etc/debian_version
10.10
root@io:~#
Nothing fancy here.
Configure stage is fine regardless if I try to specify --build and
target and host or not.
For example :
io$ date -u
Mon 09 May 2022 03:24:25 PM UTC

Really I have tried with and without the triplet arm-linux-gnueabihf and
eventually I see the same error :

Even after looking at :

I don't quite see what prerequisite is needed here.

Normally GCC won't search /usr/include/{multiarch directory} for
headers. So if you want to bootstrap GCC on a distro with such a
directory you'll need --enable-multiarch.

Maybe it's reasonable or not, Debian multiarch is described at:
https://wiki.debian.org/Multiarch/

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.

It is though. All Debian machines have been for years.
Maybe you're thinking of "multilib" which is different.

Yep. That would be what my brain was pondering. Regardless the little
armv7l unit here seems to be happily churning away on a bootstrap.
Should have a result in a few days. :\

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?

Generally multiarch directory names are encoded in gcc/config/{arch}/t-
linux* files and they have not to be exactly same as --target.
Try:
/opt/bw/build/gcc-12.1.0_debian_10_armv7l_imed.004/./gcc/xgcc -print-multiarch
This command will print the multiarch directory name. And you can
compare it with "arm-linux-gnueabihf" to see what's happening.
(The OP's mail server doesn't like me, hope he can see the thread via
list or someone can forward me.)

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.

I think my mail server has gone into full rogue mode with spamassassin
and that is the issue.
In any case I see :
io$
io$ /opt/bw/build/gcc-12.1.0_debian_10_armv7l_imed.004/./gcc/xgcc
-print-multiarch
arm-linux-gnueabi
