Dear maintainer, your package FTBFS when dpkg enables the build flag
-fdebug-prefix-map from the reproducible/fixdebugpath feature area:

Please note that the intention is to enable this build flag RSN

A quick workaround would be to disable the reproducible/fixdebugpath
buildflags with
    export DEB_BUILD_MAINT_OPTIONS=reproducible=-fixdebugpath

The real problem here is that clang 3.7 doesn't support
-fdebug-prefix-map, whilst 3.8 does.  See the blocking bug for more
information.  You might either want to wait for clang to either switch
to 3.8 or backport the patch, or to workaround it by disabling the
buildflag.
