  Ah, I mis-parsed the line:

>>> With both options, the call to __eabi is there.

  Extra suggestion: do a diff of the specs files between the two compiler
versions.  Might be informative, might not, but if you see -meabi pop up
in the differences between them you'll be on the right trail.

  Yeh, that's utterly wrong.
