I thought that the difference between arm-elf and arm-eabi is only the ABI and
not the file format of the object file.

A Debian port uses the arm-eabi:

We should use arm-elf for 4.10 since there are currently no known problems with
it.  Afterwards we can test the arm-eabi and may ship it with 4.11.
