[Pvfs2-users] building kmod on linux-2.6.22

[ryuta]

What you suggested fixed configure check but "make kmod" still fails 
with the same error. It seems that CFLAGS=... does not take effect in 
src/kernel/linux-2.6/Makefile. I'm trying to hardwire the include path 
in Makefile to force the compiler.
