It uses SUBDIRS=$(pwd), but changing that to M=$(pwd) fails in exactly
the same way.
In fact, not even manually creating the removed symlinks
in /usr/src/linux-headers-2.6.29-1-amd64 works for me, see below. Looks
like there's no -I stanza for /usr/src/linux-headers-2.6.29-1-*. And
even if I manually add -I stanzas so it can find all header files, it
still fails:
