Prefer /lib/modules/$(uname -r)/ links 

Preferentially use the /lib/modules/$(uname -r)/source and
/lib/modules/$(uname -r)/build links.  Only if neither of these
links exist fallback to alternate methods for deducing which
kernel to build with.  This resolves the need to manually
specify --with-linux= and --with-linux-obj= on Debian systems.
