I don't think VxWorks has yet switched to EABI.  In previous discussions 
on the gcc list I've suggested that the RTEMS configuration ought to 
switch, but it hasn't yet.  If the BSDs are using EABI, their 
configurations in FSF GCC haven't been updated accordingly.  (All the many 
RTOSes without special configurations in GCC may have switched from 
arm-elf to arm-eabi, of course.)
