add files System.Configuration.dll and System.Security.dll to monolite directory in tarball
to avoid: error CS0006: Metadata file `System.Security.dll' could not be found
make sure that the subdirectories of mcs/class/Facades are included in the tarball

to avoid errors like:
MCS     [net_4_5] System.Xml.Serialization.dll
/bin/sh: line 4: cd: System.Collections.Concurrent: No such file or directory
