Linux i386 2.4.12 SuSE 7.2 install. I do not think that this is
platform depedent at all, all platforms without strlcpy() should show
this.

Workaround is to edit config.h like this:

$ grep AFSLOG_UID /usr/src/arla-0.35.6-obj/include/config.h 
/* #undef HAVE_KRB_AFSLOG_UID */
#define HAVE_KRB_AFSLOG_UID

When doing the configure test for krb_afslog_uid() in arla, the test
links against -lkafs but lkafs has unresolved symbols that might be
found in libroken. Should libkafs depend on libroken? In that case,
which libroken? (Both arlas and krb1.1s seem to be sufficient).
