>Description:
Some programs do not work under emul-linux using the suse131 packages due to various levels of missing libraries and old library versions (preventing the import of missing libraries)
Main test-case: palemoon linux version

Expected: palemoon launching.
Result: segfault (Assertion failure: !rv (...))

Secondary test-case: iceweasel from debian.

Expected: able to launch iceweasel.
Result: Failure to go past Create Profile Wizard: Profile Creation Failed: Profile couldn't be created. Probably the chosen folder isn't writable.
[Exception... "Component returned failure code [...] (NS_ERROR_FILE_ALREADY_EXISTS) [...]"]
(folder is writable and profile folder does not exist until the program complains. This actually creates the profile directories, but profiles aren't recognized by iceweasel, thus it accept launching the browser).

Another attempt was made with a /emul/linux/ root based on a gentoo stage3 using cloveros binary packages for missing dependencies.
Using that setup,
glxgears segfaults on start, env vars change nothing, ktruss reports no errors, it simply receives SIGSEGV. Lynx starts but fails to connect to anything (ktruss shows err-22 on a readlink, which may be responsible). nano (included with the stage3 tarball) works fine. With all the dependencies installed, palemoon (either from the cloveros repo or as described in "how to repeat the problem") segfaults as glxgears (errors reported by ktruss are: err-38 for readahead and prlimit64).
>How-To-Repeat:
Iceweasel:
wget http://archive.debian.org/debian/pool/main/i/iceweasel/iceweasel_38.8.0esr-1~deb7u1_amd64.deb
tar -xvf iceweasel_38.8.0esr-1~deb7u1_amd64.deb
tar -xvf data.tar.xz
./usr/bin/iceweasel
(required dependencies: libevent-2.0-5_2.0.21-stable-2+deb8u1_amd64.deb libhunspell-1.3.0_1.3.2-4_amd54 libxcb-util0_0.3.8-3_amd64.deb libffi5_3.0.10-3_amd64.deb libstartup-notification0_0.12-4_amd64.deb)

Palemoon:
wget http://linux.palemoon.org/datastore/release/palemoon-28.14.2.linux-x86_64.tar.xz
mkdir palemoon && tar -xvf palemoon-28.14.2.linux-x86_64.tar.xz -C palemoon

stage3-based emul linux root:
cd /emul/linux/
wget https://bouncer.gentoo.org/fetch/root/all/releases/amd64/autobuilds/20201015T131958Z/stage3-amd64-20201015T131958Z.tar.xz
tar -xvf stage3-amd64-20201015T131958Z.tar.xz --exclude "proc/" --exclude "dev/"

tbz2 files are not .tar.bz2 but rather .tar.xz files with metadata concatenated. bsdtar can extra most, but not all of them correctly. A better approach is to get
app-portage/portage-utils-0.87.tbz2
as above, use tar to extra that one, and then use the provided linux qtbz2 as such:
usr/bin/qtbz2 -s <file>.tbz2
This produces two files, with <file>.tar.xz being of interest (simply 
tar -xvf <file>.tar.xz
to proceed).

Finally, the following test programs were installed as per the dependencies for testing:

x11-apps:
mesa-progs-8.4.0.tbz2
cd /emul/linux/
./usr/bin/glxgears

www-client:
lynx-2.8.9_p1.tbz2
cd /emul/linux/
./usr/bin/lynx
