Thank you Matthias for the pointer to the binutils patch!

For the record: when i removed those optimization options my build
succeeded and i have now built a cross compiled armv5te BIG ASM jvm
using the Jalimo cross compile infrastructure.

I will push this work into Jalimo, the project that provides
Icedtea/OpenJDK for OpenEmbedded distributions like Ångstrom, and after
then see if i can fix the OpenEmbedded binutils so that all these
optimizations can be used for cross compiled builds.
