Subject[PATCH resend 1/2] liblockdep: Use realpath for srctree and objtree
Date
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:

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

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