When running `licensecheck -r .` on the glibc source-tree, there are 
many files being licensed MIT/X11 and/or BSD 3-clause.  I don't see any 
reason Public Domain isn't suitable then.

Anyways, since Public Domain doesn't restrict relicensing, I can add a 
`LGPL v2.1 or later` license to the files in question.
