Details:

previous discussion:
http://lists.gnu.org/archive/html/bug-make/2006-03/msg00064.html

make-3.80 works ok.
3.81beta4, 3.81rc1 don't work.

Sample output with attached testcase:

/tmp/m/obj$ make --version
GNU Make 3.80
/tmp/m/obj$ make -f ../src/Makefile
mkdir -p /tmp/m/obj/dir
cc    -c -o /tmp/m/obj/dir/a.o /tmp/m/src/dir/a.c
cc    -c -o /tmp/m/obj/dir/b.o /tmp/m/src/dir/b.c
ar cru /tmp/m/obj/my.a /tmp/m/obj/dir/a.o /tmp/m/obj/dir/b.o

fails with e.g. make from cvs:
/tmp/m/obj$ rm -rf *.a dir
/tmp/m/obj$ make --version
GNU Make 3.81rc1
/tmp/m/obj$ make -f ../src/Makefile
make: *** No rule to make target `/tmp/m/src/dir/dir/a.c', needed by
`/tmp/m/obj/dir/a.o'.  Stop.
