I see a similar error in another codepath:
% apt-get source hello
% cd hello*/
% dpkg-buildpackage
⋮
dpkg-buildpackage: info: source changed by Salvatore Bonaccorso
<car...@debian.org>
Can't exec "gcc": No such file or directory at /usr/share/perl5/Dpkg/Arch.pm
line 165.
dpkg-architecture: warning: cannot determine CC system type, falling back to
default (native compilation)

I think the following patch will suffice to address it:
[[[

I tested it in current sid. I tried to build the package with this
patch, on the assumption that that would run unit tests, but the build
failed both with and without the patch with "error: cannot get project
version" (probably from ./get-version). I built by running 'pdebuild'
without arguments in a fresh debcheckout.
Cheers,
Daniel
