Got that from the thread you linked to. Do the options listed with
xxx-gcc -v show what options that is used by default och what options
gcc was compiled for and therefore supports? For example I have this:

./build_arm/staging_dir/usr/bin/arm-linux-uclibcgnueabi-gcc -v
Using built-in specs.
Target: arm-linux-uclibcgnueabi

Thread model: posix
gcc version 4.3.2 (GCC)

How do I know if the iwmmxt stuff is used by default?
