[krbdev.mit.edu #6486] t_pac fails on SPARC Solaris

[Tom Yu via RT]

During make check:

LD_LIBRARY_PATH=`echo -L../../../lib | sed -e "s/-L//g" -e "s/ /:/g"`; export 
LD_LIBRARY_PATH;  ./t_pac
t_pac: krb5_pac_verify: Invalid argument

The test passes on x86 Linux and x86 Mac OS 10.5, I believe.  I suspect an endianness problem.
