What is the motivation for doing this ?  it just looks like
overkill to me, since virArchFromHost isn't really an
expensive method to invoke.

Hey Daniel,
Thank you for the quick reply.

This patch's motivation is not about making this function faster.
Even if virArchFromHost isn't expensive, It seemed to me like there is no good reason for calling it 3 times at the same context, It is just unnecessary.
Why using a local variable instead of calling the same function three times is an overkill?

From my perspective, by calling it just once I'm making it easier for a reader to understand the usage of this function without reading its code.

Thanks in advance,
Tal Kain.
