Use PKGCONFIG to locate gssapi and rpcsecgss header files Instead of having separate copies of the gssapi and rpcsecgss header files, or depending on the Kerberos gssapi header, locate the headers now installed with the libgssapi and librpcsecgss libraries. Remove local copies of the gssapi and rpcsecgss header files. This depends on the configure_use_autotools patch.
