Configure error for krb_afslog_uid (Was: undefined reference to k_afsklog_uid)

[Harald Barth]

About the krb-1.1 + arla 0.35.6 building problem.

libkafs.a from krb-1.1 contains krb_afslog_uid() as it should.
However, arla's configure does not detect krb_afslog_uid() because the
configure test produces a linking error when linking against
libkafs.a.

Depending on what was installed before, I think the linking against
libkafs.a breaks on one or more of the following libraries: -lkrb
-ldes -lroken

The dirty workaround is to make a manual change to the generated config.h
to include 

#define HAVE_KRB_AFSLOG_UID

and rebuild aklog.o and aklog.

Harald.
