Host compiler being:
$ /usr/bin/gcc --version
gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

We do have on host a file: /usr/include/asm-generic/errno.h

At some point the "-generic" part was modified by default creating a link "asm
-> asm-target", but I am not sure now that 64 bits compiler been able to
compile 32 bits, the -generic has or not changed meaning...

In short I am not sure that is a GCC bug or a Ubuntu bug...

Looks like you don't have the 32-bit headers installed. See
https://gcc.gnu.org/wiki/FAQ#gnu_stubs-32.h

I think we should improve the toplevel configure to error out if including
errno.h fails.

So instead of:
```
    echo "int main () { return 0; }" > conftest.c
```

We should do:
```
    echo "#include <errno.h>" > conftest.c
    echo "int main () { return 0; }" >> conftest.c
```

I don't have a way to test this but this should at least cause the failure to
happen earlier during configure rather than later on.

Just reporting that the problem do not appears when --disable-multilib is asked
at the configure stage.
Unlike for ARM64 host compiling a native compiler, you need to say such
--disable-multilib for amd64 compiling a native compiler.

Well aarch64 (arm64 [which is techincally not a thing]) defaults to having only
one multi-lib (LP64) while x86_64 (amd64 which is the non-canonical name for
x86_64) defaults to having both 64 and 32bit multi-lib.

ISTR this one is what you get when you miss *linux-libc-dev*; at least it was
for Debian, and last I looked Ubuntu was still a derivative.
(Noticed last month when building a Docker suitable for gcc.)

Possibly also *gcc-multilib*
