Dear Daniel Hobi,
In message 1263834819-15315-1-git-send-email-daniel.hobi@schmid-telecom.ch you wrote:
During parallel build, the top Makefile spawns multiple sub-makes for targets in cpu/$(CPU) and $(dir $(LDSCRIPT)). If the .depend files are not present in these directories, the sub-makes may end up generating these files simultaneously which leads to corrupted content.
A typical error message is:
.depend:39: *** multiple target patterns. Stop.
This patch serializes the creation of .depend in cpu/$(CPU) and $(dir $(LDSCRIPT)) by adding these directories to the depend target in the top Makefile.
Other directories in $(LIBS) are not affected since they contain only one Make target and thus only one sub-make is spawned per directory.

v3:
- Add a comment why make _depend is required for these two subdirs
v2:
- Also build target depend in $(dir $(LDSCRIPT)) (suggested by Mike)
- Break overlong line
