You only need licences relative to the code you have chosen to use/modify.
You should keep the source headers in the code and add whatever
modification message you want
for any changes you make.
Newlib originated at Cygnus Solutions and was shipped as part of
embedded tool sets. The files you mention were originally
added/created before my time at Cygnus Solutions and do not have
specific licences in them. Normally, files without licences originally
added in the early Cygnus days (see the earliest ChangeLog entry) are
assumed to be Cygnus and now owned by Red Hat, which is the first
licence in COPYING.NEWLIB. In this case we are given the authors. The
Arthur David Olson tz code referred to by mktm_r.c is mentioned on the
net as public domain. G. Haley (author of mktime.c) is Graham Haley and
his contribution to Cygnus is noted in the libc documentation so you
will need the Red Hat licence.
