Sounds sane if one forgot to use the '--with-sysroot=' when configuring
the GNU binutils for
the target system. Here seemingly 'x86_64-linux-androideabi' when
mentioning these three multilib directories.
So the target was Ubuntu...
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 :

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...
