Quagga[-re] on mips64

[Joe Holden]

Hi chaps,

On mips64 (at least), the port produces object files instead of 
executable binaries, building with --disable-pie fixes that...

before I raise a PR, does this look good?

  CONFIGURE_ARGS+=--enable-user=${ENABLE_USER}
  CONFIGURE_ARGS+=--enable-group=${ENABLE_GROUP}


This produces a working build/package for me at least, only thing I'm 
not sure on is how that will work if mips packages are ever built for 
installation by pkg and cross-built.

Cheers,
Joe
