arch/arm: remove OABI option
OABI is more than legacy, it's dead.
New developments should go with EABI, since it so much better.
>From the Debian EABI page [0] :
- floating point performance, with or without an FPU is very much faster
- mixing soft and hardfloat code is possible
- structure packing is not as painful as it used to be
- a more efficient syscall convention
- more compatibility with various tools

[Thomas: keep the ABI choice, as we are going to introduce EABIhf later].
