I'm afraid this doesn't solve anything and you should already care about
this first problem, for it seems you're not able to create a working
executable. Putting --host just tells the configure procedure not to run
the executables (because they're meant to run on another architecture) but
the executables will be wrong anyway.

try to pass the configure a c compiler
./configure CC=gcc
or
./configure CC=xlc

and check if the error is still there

this error is linked to the first one. you shouldn't use --host

and also this. I suggest to solve the above problems first f.
