Creating 32bit AppImage is mixing 64bits libs and failed executing with 'oosplash: Exec format error'

[sputnick-dev]

Used this command line to install libreoffice:

$ ./make_libreoffice_appimage.sh daily x86 standard N Y N Y

The created binary is 32bit:

$ file AppRun 
AppRun: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=1e71ee80b1855ddde430cde2857f6ce3a7a3bb33, with debug_info, not stripped

while the libs are 64bit:

$ ./AppRun 
/PATH/LibreOfficeDev/LibreOfficeDev.AppDir/usr/bin//libreofficedev7.4: 191: exec: /PATH/LibreOfficeDev/LibreOfficeDev.AppDir/opt/libreofficedev7.4/program/oosplash: Exec format error
$ file /PATH/LibreOfficeDev/LibreOfficeDev.AppDir/opt/libreofficedev7.4/program/oosplash
/PATH/LibreOfficeDev/LibreOfficeDev.AppDir/opt/libreofficedev7.4/program/oosplash: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=f60aed35eb866e2b73386fcbff8b84e8a58a378e, stripped

Even a ls is showing x86_64 libs:

I use Debian10 on a 32bit computer and trying to install on a pendrive
