[Debian-med-packaging] Bug#949379: vmatch: please make the build reproducible

Source: vmatch

Hi,

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

Patch attached that ensures that the vmrelease.h file does not contain
the build time and the hostname of the build system.

However, vmatch remains unreproducible even when this is applied. My
best guess at this moment is because it is not actually being built
with the -fdebug-prefix-map=... GCC argument in places:

  $ grep 'gcc ' build.log | grep -v prefix-map | wc -l
  348

… in other words, it is not respecting CFLAGS / dpkg-buildflags.
