* Increase stack size when using musl libc on Alpine
This is probably not the best way to do it in long run, but I'm not sure
how to detect libc version at compile time.
* Fix free-check bug on Alpine
* Extra symbols in shared library on Alpine
* Activate Alpine builds
* Only increase stack size if musl is present on Alpine
This is not the most generic way to do it but hopefully will suffice
* Temporarily enable Alpine builds
* Simplify link option on Alpine
