curl on F-8 isn't built with GSSAPI Negotiate support. This is a regression from
Fedora 7.

GSSAPI support is enabled in %configure but the lack of libraries causes it to
not get configured. I did a test and added krb5-devel to BuildRequires and that
was enough to get negotiate working in a mock build.

Here is my change:
