Subject[PATCH] Use realpath for srctree and objtree
Date
When BUILD_SRC contains a tailing '/', the file name used in compiling command
will contain '//', and it then goes to .o's debuginfo, confuses debugedit:

https://bugzilla.redhat.com/show_bug.cgi?id=304121

This patch uses realpath to makesure srctree and objtree don't have tailing '/'.
