Bug#953071: ndisc6: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
ndisc6 could not be built reproducibly.

This is because it includes the CFLAGS used to build the package in
the binary via PACKAGE_CONFIGURE_INVOCATION which then includes the
absolute build path via (eg.) the -ffile-prefix-map flag.

I see you already patch out the hostname, etc. and you could follow
this approach and remove the CFLAGS too, but just in case they might
be useful I've attached a patch that strips out the -fdebug-prefix-map
(etc.) calls instead.
