Subject: [PATCH] - fix wrong path to scripts/usage; It is in the builddir and
 not in the srcdir. - flag .depend as .NOTPARALLEL to workaround bug in
 make-3.80 and make-3.81 Some more details on the second workaround (i.e.
 kludge): make-3.80 silently fails, while make-3.81 is at least self-conscious
 enough to admit: include/usage_compressed.h: .config scripts/usage # 
 Implicit rule search has not been done. #  File does not exist. #  File has
 not been updated. #  Dependencies commands running (THIS IS A BUG). # 
 commands to execute (from `/home/cow/src/bb2/Makefile', line 430):        
 $(Q)$(SHELL) $(top_srcdir)/scripts/usage_compressed "$(top_builddir)/scripts"

I'm giving up on trying to run the rest of the prerequisites of .depend in
parallel and just (try to) indicate that the prerequisites of .depend are
not to be run in parallel.

While this makes `make distclean defconfig;make -j´ work for me, it is not a
real -- longterm -- solution; FIXME
