Last lines of compilation

I ran CC=gcc-4.6 ../gcc-4.8.0/configure
--prefix=/home/prosfilaes/bin/gcc-4.8.0/
--enable-languages=ada,c,c++,java,fortran
and then
make bootstrap
It fails with

Poking at it, this seems to be telling me that I don't have a 32-bit
development package installed, which is true, but shouldn't it stop at
configure and tell me that instead of erring out in the middle of compilation
with an unhelpful error message?
