# When doing the initial ./config target-platform a file, ".config"
# will be created in the B2G root containing this line
# "GECKO_OBJDIR=/home/user/path/to/B2G/objdir-gecko"
# So when building at one stage, GECKO_OBJDIR is going to be created
# which will fail since we are running as a normal user, not root.
# To solve we simply give ownership to /home to build user.
