Nalin Dahyabhai 2202e378de - build shared libraries with partial RELRO support (#723995)
- filter out potentially multiple instances of -Wl,-z,relro from krb5-config
  output, now that it's in the buildroot's default LDFLAGS

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*, PIE flags, and CFLAGS 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.
