Thanks! It would be great if ".."s in object pathnames could also be
supported in the forth coming re-post.

I have some external modules which link with object files outside their
directories. For example, a source tree looks like

module0/main.c
lib0/lib.c

and the Kbuild file has to use

main-y += ../lib0/lib.o

to link in lib.c. Current gcov-kernel does not support ".." in
pathnames. Could ".."s be handled in add_node?
