You can spy how the current GCC was configured via 'gcc -v'.  I could 
guess a 'mipsel-linux-gnu' or
'mipsel-linux-gnueabi' being used in its configure command. Or things to 
define the default output
and CPU to be a 32-bit one instead of the expected 64-bit....

Just for curiosity I checked what the 'gcc-4.3_4.3.5-4_mipsel.deb' 
package from 2012 (like your
system) was and saw it being configured using all the three system names 
being the same :

     --build=mipsel-linux-gnu --host=mipsel-linux-gnu 
--target=mipsel-linux-gnu

(using 'strings gcc-4.3 | less' and searching for 'configure')  You 
should check also the other options
used with the existing native GCC  whether they could be needed...
