[PATCH] tools lib traceevent: Use realpath for srctree and objtree

From: Wang Nan
Date: Thu Feb 06 2014 - 23:25:57 EST

If BUILD_SRC or CURDIR contains tailing '/', the file names passed to gcc will
contain '//'. It will be contained .o's in debuginfo, then confuse debugedit:


This patch uses realpath command to makesure potential tailing '/'s are removed.
