Build binaries in this package as RELRO PIEs 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.
