From 30fd45adb2e54c7369505ac840907dc33a1078fa Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 19 Jun 2012 15:55:38 +0100 Subject: [PATCH] Makefile.hw: avoid overly large 'make clean' rm command Avoid 'make clean' producing an 'rm' command which has a lot of duplicate 'hw//*.o' arguments, by using $(sort $(dir ..)) rather than $(dir $(sort ..)) so Make's sort function will remove the duplicates for us. We can also remove the double '//' safely because $(dir ..) is guaranteed to return a string ending in '/'.
