`Documentation/kbuild' directory in your linux sources.
`makefiles.txt' about `lib-y',
`modules.txt'   about modules.

A sample Makefile:
KDIR    := /lib/modules/$(shell uname -r)/build


obj-m += test.o
test-y := hello.o libhello_lib.a

all:
   gcc -I/usr/include -c -o hello_lib.o hello_lib.c
   rm -f libhello_lib.a
   ar cru libhello_lib.a hello_lib.o
   $(MAKE) -C $(KDIR) SUBDIRS=$(CURDIR) modules KBUILD_VERBOSE=1


Also, keep in mind that you can link a static library and not a shared
library in a kernel module.
Shared libraries can only be accessed in user space.
