[ArsenShnurkov]

Steps to Reproduce

#!/bin/bash

#WORKDIR=/var/tmp/tarballs/dotnet/dev-lang/mono
WORKDIR=/1

rm -rf ${WORKDIR}
mkdir -p ${WORKDIR}
git clone https://github.com/mono/mono.git ${WORKDIR}
cd ${WORKDIR}
git submodule update --init --recursive
git reset --hard f93caff1c85d74db8561d951b96d5dde9dea8bd5
./autogen.sh
#./configure
make
make dist

Current Behavior

tar: Exiting with failure status due to previous errors

Expected Behavior

I expect these files to be included into archive

Could you please try the following patch which removes these files from the tarball (we don't use them during the build, only tests) and should workaround the problem:
