0.8.1: bug fixes for ARM

This is mostly a bug-fix release. Thanks to @bmegli, @joerg-krause , and @rofl0r the builds on ARM are now confirmed to work.

Fixes:

• fix for musl build thanks to @joerg-krause
• resolved #19, #22, #23, #28
• info screen: replace interval timer with pthread
• fixed an illegal free (found on ARM), which seems to also have caused a memory leak on ARM.
