If you have only 2 cores, then -j4 is not really useful, is it? You
will never have more than 2 jobs running at the same time. I think
the usual rule of thumb is to use 1.5 times the number of cores as the
argument to -j. In your case, that would be -j3.

Thanks. I think your problem begins with this error message I see in
the log:
mkdir: impossibile creare la directory "deps": File exists
This comes from the following fragment in src/Makefile.in:
.c.o:
@$(MKDEPDIR)
$(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
where MKDEPDIR expands to this:
test -d ${DEPDIR} || mkdir ${DEPDIR}
Now, if more than one .c.o rule tries to create the `deps'
subdirectory at the same time, one of them might lose due to a race
condition, and fail the entire compilation.
Could you please try changing this line:
@$(MKDEPDIR)
into
-@$(MKDEPDIR)
and see if that makes the problem go away?
