glibc will use things in newer kernels anyway.  You don't need to use 
NPTL_KERN_VER=2.6.38 in order for glibc to use 2.6.38 features; it will 
do that by default.  NPTL_KERN_VER only omits fallbacks for older 
kernels.  It's there to reduce the size of glibc.  The size difference 
is very small though.
