Unfortunately, yes, due to licensing and because we don't have a
liblinux with the things in tools/lib/*.c, we need to relicense that as
at least LGPL 2.1 :-\

Lets start here, whoever reads this message, would you have a problem
with relicensing what is in tools/lib/*.c and tools/lib/api/ as LGPL
2.1?
