Cool.

Well I suppose it depends how you chop your disc up, personally I put
/usr and / on the same partition and made them fairly small and made
/usr/local and /discs/cross - but its just a matter of taste I guess.

Hmm that didn't work for me - I get complaints at the end of the build
complaing from dh_strip about an unkown output file format.
(I did the shlibdeps change after using dpkg-cross and after building
binutils but before building gcc).

P.S. Here is a script I wrote to get the libc6 and libc6-dev packages
for dpkg-cross - there must be an easier way?
