Bug#961009: nulib2: please make the build reproducible

Source: nulib2
Version: 3.1.0-2
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
nulib2 could not be built reproducibly.

This is because it embedded the build flags into the generated binary
which then included the absolute build path via the -ffile-prefix-map
GCC argument.

Patch attached that overwrites this from debian/rules via the
DEB_CPPFLAGS_MAINT_APPEND mechanism and sets it to an empty string but
it may be nicer to replace this with something like "Debian" or
something.
