Sorry, wrong answer. You have not told configure the proper compilation
prefix, so, it failed finding "arm-linux-gcc", and fall back to gcc.
Unfortunately, gcc is not able to generate arm code, only
arm-none-linux-gnueabi-gcc is.

pass --host=3Darm-none-linux-gnueabi to configure, or pass a value for CC=

on configure command line.
