This problem is caused by including -ltirpc, where libtirpc.la lists -lgssglue as a dependency.  Libtool (2.2.6b) then re-evaluates the order of linked libraries putting libgssglue behind libgssapi_krb5.

I fixed this by specifying -lgssglue with -Wl, which is ignored by libtool:

GSSGLUE_CFLAGS="-Wl,-lgssglue" ./configure
