[CROSS] Fix generation of debian/control

How to check:

echo armel >debian/target
debian/rules control

look at debian/control - libgcc1-armel-cross and libgcc1-dbg-armel-cross will be broken

seems tooling related, I thought foundations would want to take a look

fixed in 4.6.2-12ubuntu1

dpkg-gencontrol: error: syntax error in debian/control at line 48: block lacks the 'Package' field

debian/control.m4 needs lot of fixes to get cross build working again. My brain shutdown each time when I see m4 ;(

I am thinking about adding NOTARGET variable to reverse some of checks there.

Build of cross compiler gave me few more errors from dpkg so I had to change debian/control.m4 a bit.

should the conflicts to libhfstdc++6-dbg`'LS really be dropped?
