I'm OK for removing it atm but going forward we cannot pretend such
configurations do not exist. For example, if someone wants to build
Samba AD on RHEL/CentOS using Heimdal but keeping the rest of the system
with MIT Kerberos, a default system krb5.conf is utilizing includedir to
implement crypto defaults.
In a sense, Volker's follow up patch is a better direction because it
supports includedir operation.
