Looks to me like you have no /usr/src/Makefile.

None of the information you provided in your above output, however,
shows anything about the filesystem (other than /usr/bin/make).  But
this sounds honestly like some sort of corrupted supdb, or a cvsup
mirror that's broken.

I would do the following:

rm -fr /usr/src/*
rm -fr /var/db/sup/src-all
csup -h <cvsupserver> -L 2 -g /usr/share/examples/stable-supfile

I can assure you /sys/amd64/conf/GENERIC exists, and is on the cvsup
mirrors.

Superblock problems wouldn't explain this; there are hundreds of
superblocks available (you wouldn't be able to use your machine if they
were all horked).
