It seems you might have specified --host incorrectly, replace
your --host and --target options by the followings:

--build=i386-unknown-linux-gnu --host=alpha-unknown-linux-gnu

(see 
http://www.gnu.org/software/autoconf/manual/autoconf.html#Specifying-Target-Triplets)

Be sure to do a "make distclean" before reconfiguring mpich2.
If the problem persists, send us the configure and make outputs
as seen on your terminal (It is possible that cross-compile support
is still buggy)

BTW, your stderr message should be piped to the configure output
file as it will help us to identify any potential problem/bug faster.
If you are not familiar with piping stderr and stdout to 1 file,
see the mpich2's README or installer's guide.
