This is your problem. 
The host is the machine you're going to run the compiler on, ie. it should be 
the same as the build machine when building a cross compiler.
eg. --build=i686-pc-linuc-gnu --host=i686-pc-linux-gnu --target=rdos
I generally specify all three as the defaults sometimes do unexpected things.

If you're trying to build a native hosted rdos compiler you need to have an 
rdos targeted (native hosted) cross compiler already in your path. This 
compiler will be used to build the target libraries.

I suggest you look at crosstool. This knows all the steps required to build a 
cross toolchain.
