_CS_PATH is not defined on termux see https://github.com/search?q=repo%3Atermux%2Ftermux-packages%20_CS_PATH&type=code

pthread on android doesn't implement some function see https://github.com/search?q=repo%3Atermux%2Ftermux-packages%20pthread&type=code

On the C side, conditional compilation like ifdef on _CS_PATH and ifndef on __ANDROID__ could be used.
On scala side, what could be used to detect environment in the posixlib?

What is the best to use to have different logic on Termux?

With Scala Native 0.5.5 and multi threading default off I only saw the error about _CS_PATH

_CS_PATH is resolved in #4037 Now what to do with PTHREAD?

We are not always using pthread. It is still is always required when using java.lang.Thread or Commix GC, but in the remaining cases we should be able to skip it from the linked libraries. I've made some initial PR to test this concept, but there is only 1 remaining thing - testing Android in the CI and for that we would need to integrate and automate setting up Android environment. I can link the binary, but I cannot run it yet.
