This update fixes the following issue with libtirpc:
- bnc#841788:
+ Change BuildDepends from krb5-devel to krb5-mini-devel for those releases which provide it as the later is sufficient and has fewer down-stream dependencies.
+ Use krb5 rather than gssglue to provide gss access routines. Both krb5 and gssglue provide routines of the same name, and both can get linked into rpc.gssd, resulting in some confusion. Upstream support seems to be leaning heavily towards avoiding libgssglue. nfs-utils is built without it, and best to build libtirpc without it.
