+configure: Allow overriding uname results
- Use values exported from $(TOPDIR)/rules.mk for determining
- the target system instead of the host configuration
+In a cross compile setting it makes no sense to rely on the "uname" values
+reported by the build host system. This patch allows overriding the
+"uname -r", "uname -s" and "uname -m" results with the "UNAME_R", "UNAME_S"
+and "UNAME_M" environment variables.
