Dear siesta users

I am trying to install siesta in parallel but after editing my arch.make
file as given below when I try to make it it will  shown me the error
Compilation architecture to be used: x86_64-unknown-linux-gnu--unknown
If this is not what you want, create the right
arch.make file using the models in Src/Sys

Hit ^C to abort...
