gcc-4.2-multilib is noisy on i386

[Daniel Schepler <schepler@math.unipd.it>]

Whenever I use gcc-4.2-multilib to compile an amd64 program on i386, at the 
link stage I get a message:

/usr/bin/ld: error 
in /usr/lib/gcc/i486-linux-gnu/4.2.1/64/crtend.o(.eh_frame); no .eh_frame_hdr 
table will be created.

The command returns successfully, so this is mostly harmless, except that it 
causes zlib to FTBFS because zlib's configure script is badly behaved and 
treats any output as an error.  I was wondering whether you might know what's 
causing this message.
