    Fix more parallel make races
Makefile:  dodgy dependency fix

Despite the '%/.stamp-linux-ppa: %/.stamp-linux' dependency, 'make
DEBBUILDOPTS=-j16 <distro>/<arch>/.stamp-kmodule' doesn't build the
kernel first.  Explicitly add.
Lucid i386 build segfaults on /usr/bin/make; remove lucid

Bizarre, since this used to work, and amd64 still works.

Lucid is EOL, so just remove it.  Hopefully this will fly with the MK
community....

    Set /lib/modules/<kver>/build link

    This was lost in 051c8cd, 'Fix postinst script that breaks kernel
    module builds'.  The package's build link points to
    /tmp/buildd/linux-source... instead, agh.
include libfile-fcntllock-perl in pbuilderrc to silence warnings

Warnings:

    dpkg-gencontrol: warning: File::FcntlLock not available; using
    flock which is not NFS-safe

This seems like it ought to be installed as a dependency of dpkg-dev,
which packages dpkg-gencontrol.
pbuilderrc:  only include libfile-fcntllock-perl for wheezy
Re-enable lucid

False alarm in 4e2ee160; problem is -j16 breaks make-kpkg.  :P
