New Revision: 235929
URL: http://svn.freebsd.org/changeset/base/235929

Log:
  Allow building for the PowerPC EABI by providing a dummy __eabi()
  function. The purpose of the __eabi() function is to set up the
  runtime and is called first thing by main(). The runtime is already
  set up for us prior to caling main, so there's nothing to do for
  us in the EABI case.
