Check for environment variables that you might have set and forgotten 
about.  An environment variable set for native gcc may also be used for 
cross gcc.

Check the .i file for accidental uses of /usr/include.  There might be a 
problem with your arm cross compiler using /usr/include when it 
shouldn't.  You can also see the header file search dirs by adding -v to 
the compiler command.

You might try using someone else's build scripts that are known to work, 
for instance crosstools-NG.
