Last when I tried this target there weren't the 'x32' libraries, only
the 32- and 64-bit ones.
So maybe it was the time to try a newer Ubuntu target. The "22.04.2"
seemed to be suitable
to try.
As you told, the target headers and libraries seemed to be a big mess
when looking in which
packages they were delivered. The "Desktop" release ISO-package seemed
to provide only a
subset and one needed to look at the "pool/main" archives. The Ubuntu
mirror in Finland had
even this somehow "stripped" because I got this error when trying
gcc-11.4.0 for
the 'x86_64-ubuntu-linux22.04' target :
In file included from
/opt/host-x86_64-ubuntu-linux22.04/usr/include/bits/errno.h:26,
from
/opt/host-x86_64-ubuntu-linux22.04/usr/include/errno.h:28,
from ../../../../libgcc/../gcc/tsystem.h:93,
from ../../../../libgcc/libgcc2.c:27:
/opt/host-x86_64-ubuntu-linux22.04/usr/include/linux/errno.h:1:10:
fatal error: asm/errno.h: No such file or directory
1 | #include <asm/errno.h>
| ^~~~~~~~~~~~~
compilation terminated.
The 'kernel headers' were from the two
'linux-libc-dev_5.15.0-78.85_*.deb' packages but something
was missing for the '-mx32' case. Earlier there were a faulty symlink
to '/lib/ld-linux.so.2' or what the
32-bit one is. Of course this shouldn't be to the absolute '/lib' but
to the relative '../lib'. And all the
32-bit headers were missing, the desktop-image providing only a
'linux-libc-dev_5.15.0-60.66_amd64.deb'
package for which the 'linux-libc-dev_5.15.0-60.66_i386.deb'
equivalent wasn't found. Therefore using
the '78.85' packages. Let's see whether the found
'linux-headers-5.15.0-78-generic_5.15.0-78.85_amd64.deb'
has all the required headers...
This problem seemed being seen earlier by others. And the solution being
one kind of "hack" :
"Try installing |gcc-multilib|
@doug that's *the* solution. Funnily enough, all this package contains
is a symlink||
|/usr/include/asm -> x86_64-linux-gnu/asm|.
If you post this as an answer, I'll accept it."

The options used to configure the original Ubuntu 22.04 GCC which I
partly copied without
first reasearching what they will do caused more errors during the
build. Like the missing
'include/crypt.h' when the provided target libs didn't have zlib.
