This needs to be --target=i386-rtems4.10

There are 2 mistakes with dramatic consequences in your invocation of 
configure:
a) a blank between "--target=" and "i386"
b)"i386" not a valid target for RTEMS.

Though the value passed to --prefix can be arbitrarily chosen, you on 
one hand seem to be trying to build rtems-4.10, but on the other hand 
seem to be intending to install into a "rtems-4.11" directory.

As RTEMS 4.10 and RTEMS 4.11 are quite different and require different 
toolchains, so mixing them will rarely work.
This doesn't seem wise to me.

These likely are all follow-ups to how you specify "--target= "
