[patch] install host specific {bits,ext}/opt_random.h headers in host specific c++ incdir

[Matthias Klose]

{bits,ext}/opt_random.h became host specific in 4.8, but are still installed
into the host independent c++ include dir.  install them into the host specific
include dir instead.  Ok for 4.8 and trunk?
