Fixing volume_id Makefile for parallel make

Hi!

Calling parallel make with ugly options to allow forking real huge number of processes seems to break on machines with more cpus.

CC .shlib/squashfs.o
CC .shlib/vxfs.o
Assembler messages:
FATAL: can't create .shlib/util.o: No such file or directory

  CC       .shlib/ocfs.o
  CC       .shlib/luks.o
  CC       .shlib/gfs.o

Assembler messages:
FATAL: can't create .shlib/netware.o: No such file or directory make[2]: *** [.shlib/util.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: *** [.shlib/netware.o] Error 1

As compiling .shlib/*.o needs the directory .shlib, but it does not state that in makefile:

Only this command list .shlib as dependency:
$(SHLIB): $(HEADERS) .shlib $(addprefix .shlib/,$(OBJS))

But make knows that .shlib/*.o does not depend on .shlib explicitly .shlib/%.o: %.c

changing that to
.shlib/%.o: %.c .shlib
makes it no longer fail on missing directory.
