remove left over function

There may be certificates that lack a trailing newline, which is allowed
in the certificate format. We work around that by inject a newline after
each cert.

we need ca-certificates when bootstrapping new architectures. Avoid use
of python to reduce number of dependencies when bootstrapping.

So use mk-ca-bundle.pl script from curl, and add a small shell script
that splits the bundle to separate .crt files, similar way that the
python script did.

musl removed SYMLINK_MAX define[1]. Use PATH_MAX instead for symlink
target.
