The inferred value is incorrect for many systems. For example, Probably all
linux-musl users need to set LLVM_DEFAULT_TARGET_TRIPLE correctly, since the
default guessed value isn't correct for them.
```
% grep -A1 s390x:Linux llvm/cmake/config.guess
s390:Linux:*:* | s390x:Linux:*:*)
echo ${UNAME_MACHINE}-ibm-linux
```
Since you have access to s390x, perhaps you can test a change to
`llvm/cmake/config.guess`
```
if [ "$(grep -Ei 'debian|ubuntu' /etc/lsb-release)" ]; then
echo ${UNAME_MACHINE}-unkown-linux-gnu
else
echo ${UNAME_MACHINE}-unkown-linux-gnu
fi
```
