They may already have been downloaded, but they do not get installed
into the chroot.

As it happens zlibg1-dev has not been installed. dpkg reports:-
david@voyager:~/emdebian/trunk$ dpkg -l "zlib1-dev*"
|/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err:
||/ Name Version Description
un zlib1-dev <none> (no
un zlib1-dev-i386-cross <none> (no
So I am not quite sure why apt-cross thinks it has been.
david@voyager:~/emdebian/trunk$ apt-cross -a mipsel -l zlib1g-dev-mipsel-cross
david@voyager:~/emdebian/trunk$ apt-cross -a mipsel -s zlib1g-dev-mipsel-cross
apt-cross: Unable to find zlib1g-dev-mipsel-cross.

Well the failures I get are to do with the failure to install zlib1g-dev.
libz.so is not found, and the relevant headers are not found. So it looks
as though although apt-cross may think it is installed, it has not been. But
there are no other errors or warnings between these and the failure.
At the point of failure I get:-
checking for strings.h... yes
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
checking for gzdopen in -lz... no
configure: error: zlib library not found
See `config.log' for more details.
make: *** [build-tree/config.status] Error 1
dpkg-buildpackage: failure: debian/rules build gave error exit status 2
And zlib should have been installed which is part of zlib1g-dev.. This worked
just fine with the i386 build, this is the first time I have tried a cross
