[Reproducible-builds] Bug#827155: dpkg-buildflags: reproducible/fixdebugpath doesn't escape build path

[HW42]

Package: dpkg-dev
Version: 1.18.7

Hi,

as Mattia noticed dpkg-buildflags doesn't escape the build path in the
-fdebug-prefix-map CC argument when enabling the 'fixdebugpath' option.

What assumptions does dpkg make about the build path? I think there are a
lot of build scripts which anyway break if the build path contains a
space.

Unfortunately this isn't trivially fixed since the flags are
concatenated as a string and later exported in different languages
(shell, Makefile). So if we want to support spaces in buildpaths this
need to be changed to an array. What do you think?
