From 5c1fe562d8044249f5830df826544bc72ecb41b2 Mon Sep 17 00:00:00 2001
From: Andrew Robbins <contact@andrewrobbins.info>
Date: Thu, 26 Oct 2017 21:45:42 -0400
Subject: Remove unnecessary spaces in command substitutions

This is likely one of the very last changes necessary to make the
Libreboot build system more cohesive in appearance.

Hopefully from this point forward it won't be as readily apparent as
to who wrote which parts of the build system (i.e. won't look like a
patchwork quilt any longer).
