Actually the symlinks don't need to be broken. It fails for any kind of symlink
on musl.
$ ls -l /tmp/symtest
lrwxrwxrwx 1 mcrees mcrees 10 Apr 18 21:16 empty -> /var/empty
-rw-r--r-- 1 mcrees mcrees 0 Apr 18 21:16 regular
lrwxrwxrwx 1 mcrees mcrees 16 Apr 18 21:16 resolv.conf -> /etc/resolv.conf
$ python3
>>> import shutil; shutil.copytree('/tmp/symtest', '/tmp/symtest2',
>>> symlinks=True)
shutil.Error: [('/tmp/symtest/resolv.conf', '/tmp/symtest2/resolv.conf', "[Errno
95] Not supported: '/tmp/symtest2/resolv.conf'"), ('/tmp/symtest/empty',
'/tmp/symtest2/empty', "[Errno 95] Not supported: '/tmp/symtest2/empty'")]
$ ls -l /tmp/symtest2
total 0
lrwxrwxrwx 1 mcrees mcrees 10 Apr 18 21:16 empty -> /var/empty
-rw-r--r-- 1 mcrees mcrees 0 Apr 18 21:16 regular

The implication of these bugs mean that things like pip may fail if it calls
shutil.copytree(..., symlinks=True) on a directory that contains symlinks(!)
Attached is a patch that works around the issue but does not address why chmod
is returning OSError instead of NotImplementedError.
