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
