File krb5-1.12-buildconf.patch of Package krb5.12021

Build binaries in this package as RELRO PIEs, libraries as partial RELRO,
and install shared libraries with the execute bit set on them.  Prune out
the -L/usr/lib* and PIE flags where they might leak out and affect
apps which just want to link with the libraries. FIXME: needs to check and
not just assume that the compiler supports using these flags.
