How to remove –with-mode=thumb from linaro

Hi

I am using Linaro gcc on Ubuntu/ARM. I am having a problem in building a package that does not support thumb nor thumb2. When I typed "gcc -v" I saw that "–with-mode=thumb" and I assume that means my gcc compiler will try to optimize some code in thumb. So I assume I need to make my Linaro compiler knows that no thumb! Please correct me if I were wrong.

What flag I have to pass in making? I mean what to type in after CCFLAGS= in make or what to be added in Makefile. Thanks!
