# XXX: I really, really hate this...  but to ensure the kernel build 
# system compiles C files shared between a library and a kernel module, 
# we need to ensure each file has a unique make target.  To do that 
# I'm creating symlinks for each shared file at configure time.  It 
# may be possible something better can be done in the Makefile but it
# will take some serious investigation and I don't have the time now.
